This construction

264-460: A Portuguese captain sailing for Spain, Sebastião Rodrigues Soromenho (Spanish: Sebastián Rodríguez Cermeño) explored some of the same coastline, leaving a description of coastal features. The Portolà expedition carried a copy of Soromenho's writings to guide them along the coast. Soromenho was followed in 1602 by Sebastián Vizcaíno , whose coastal explorations in 1602 surveyed several California locations for future colonization, including San Diego,

352-480: A dozen Indians from the interior – apparently Rumsen people  – visited, bringing pinole and seeds. The next day the party slaughtered a mule, but not everyone would eat it. The weather turned cold, and snow began to cover the hills. The exhausted men reached San Diego on January 24, 1770 "smelling frightfully of mules", but warmly welcomed by their fellow soldiers and friars. Apart from five men who had apparently deserted, every member of

440-415: A harbor with a ship laden with food supplies. Heading a party of scouts up and over Montara Mountain , Ortega reached the area now known as Devil's Slide .

Ortega and his scouts turned back south along the west shore of the bay, around the southern end and back up

528-545: A joint land-sea movement up the Pacific coast. The job of the ships was to keep the land contingent supplied with provisions and to carry communications between them and New Spain. Portolà decided to travel by land. The expedition's original assignment was to travel to the "port of Monterey" described by Vizcaíno and establish a settlement there. After that, the explorers were to continue north to locate Soromenho's "Bay of San Francisco", chase away any Russians encountered, claim

616-428: A large wooden cross where passing ships could see it, with a letter describing the expedition's travels buried at its foot. Crespí quoted part of the letter: "The cross was planted on a hill on the edge of the beach of the little bay which lies to the south of Point Pinos (pine-covered headland)." Frustrated in their hunting and fishing efforts, men of the expedition had to eat seagulls and pelicans. On November 30, about

1056-436: A source of fresh water and helped by Indians they encountered, they found a suitable river about nine miles northeast. Moving their ships as close as possible, they set up a camp on the beach, surrounding it with an earthen parapet with two cannons mounted. From their ships' sails and awnings they made two large hospital tents, as well as tents for the officers and friars. Then they moved the sick men to shore and settled them into

1144-606: A stock of supplies for the new mission in Monterey. Buffeted by unfavorable winds, the San Antonio retreated back south to Baja California , then swung as far north as the Farallon Islands , 100 miles (160 km) northwest of Monterey. Several sailors fell sick with scurvy . The San Antonio finally sailed into Monterey Bay on May 31, welcomed by the Portolà party which had arrived a week earlier. They returned to

1232-515: Is in the Mainside Complex, at the southeastern end of the base, and the remote northern interior is an impact area. Daytime population is around 100,000. Recruits from nearby Marine Corps Recruit Depot, San Diego spend four weeks at Pendleton's Edson Range receiving field training; after graduating from recruit training , newly minted infantry Marines return to the base's School of Infantry for further training. Camp Pendleton remains

1320-410: Is one more encroachment venture that will hinder [our] ability to prepare for war. It will also result in additional losses of natural areas that support endangered species, thus placing an even greater burden on Camp Pendleton to protect the region’s biodiversity.” In 2008, after the rejection of the proposed toll road extension of SR 241 through San Onofre State Beach Park for environmental reasons,

1408-500: Is ongoing. The original ranch house has been declared a National Historic Site as well as the Las Flores Adobe . The base's diverse geography, spanning over 125,000 acres (506 km ), plays host to year-round training for Marines in addition to all other branches of the U.S. military . Amphibious and sea-to-shore training takes place at several key points along the base's 17 miles (27 km) of coastline. The main base

1496-423: Is the port of Monterey without the slightest doubt." The three men then walked along the rocky coast south to Carmel Bay . Several Indians approached them, and the two groups exchanged gifts. Meanwhile, on April 16, the San Antonio , captained by Juan Pérez , set sail from San Diego to Monterey. On board were friar Junípero Serra , cartographer Miguel Costansó , and doctor Pedro Prat – along with

1584-662: The 1996 Republican National Convention , accompanying national anthem performers. Among the more famous performers who were accompanied by the Camp Pendleton color guard have been Frankie Laine , Herb Alpert , Wilson Phillips , Jewel , Trisha Yearwood and the Dixie Chicks , all of whom had performed the National Anthem at either a World Series game, Super Bowl , or, in Wilson Phillips' case,

1672-538: The 9th Marine Regiment , under then Colonel Lemuel C. Shepherd Jr. , marched from Camp Elliott in San Diego to Camp Pendleton to be the first troops to occupy the new base. On September 25, 1942, President Franklin D. Roosevelt officially dedicated the base. Wartime training facilities at the base included landing craft school, amphibious tractor school, beach battalion school, amphibious communications school , Naval Construction Battalion Training Center and

1760-690: The British had been pushing west in Canada and were approaching the Pacific coast. In order to secure Spain's claims in California, Charles III wanted to explore and settle the coastline so that he could create a buffer zone to protect Spain's territories from the threat of invasion. Upon hearing about the king's desire to explore Alta California , New Spain's visitador (inspector general) José de Gálvez organized an exploratory expedition and placed Governor Portolà in overall command. The plan called for

1848-598: The California Channel Islands and Monterey . Vizcaíno sailed north from Mexico (as Cabrillo had done), a much more difficult undertaking because of the prevailing winds and ocean currents. After Vizcaíno, however, the Spanish Empire did little to protect or settle this region for the next 160 years, and accomplished almost no exploration by land. Affairs in Europe took precedence, keeping all of

1936-555: The Franciscan missionary team into Alta California, joined the Portolà party as chaplain and diarist. The 55-year-old Serra suffered a chronic infection of his left foot and leg, which Portolà believed had now become cancerous. He tried to dissuade Serra from joining the expedition, but Serra refused to withdraw; he told Portolà to go ahead, saying he would follow and meet up with Portolà on the frontier. Meanwhile, Serra assigned friar Miguel de la Campa from Mission San Ignacio to join

They found the cross surrounded by feathers and broken arrows driven into the ground, with fresh sardines and meat laid out before the cross. No Indians were in sight. In the bay waters, hundreds of seals and sea otters splashed and basked in the sun. Crespí wrote: "This

2200-496: The San Carlos headed south down the Gulf of California to round Cabo San Lucas and then head north along the Pacific coast. On February 15, Gálvez dispatched the San Antonio , captained by Juan Pérez , from Cabo San Lucas; Franciscan friars Juan Vizcaíno and Francisco Gómez served as chaplains. With sailors plus cooks, carpenters and blacksmiths, the San Antonio carried a total of around 30 men. These ships left ahead of

2288-719: The United States Navy and the Fallbrook Public Utility District . In August 2018, the Fallbrook Public Utility District sold its land on the river, ending its over 60-year plan to place a hydroelectric dam on the river; it will be preserved by the Wildlands Conservancy , which utilized funds from bonds authorized by Proposition 68 to purchase the land. The mainstem of the Santa Margarita River begins at

2376-424: The "port of San Francisco" by previous European explorers, while what is today known as "San Francisco Bay" was still undiscovered. The sight convinced some, but not all of them that they had indeed bypassed the port of Monterey. Sergeant Ortega , contacting a group of Indians, thought they were trying to notify him of a ship anchored somewhere up north; for weeks, the men of the expedition had sought desperately for

2464-487: The 122,798 acres (497 km ) of Rancho Santa Margarita y Las Flores would be transformed into the largest Marine Corps base in the country. It was named for Major General Joseph Henry Pendleton who had long advocated the establishment of a West Coast training base. Construction began in April as a temporary facility built to minimum standards of wood frame construction. After five months of furious building activity,

2552-534: The Jesuits and replace them with Franciscans , who would set up their own network of missions in the colony. Gaspar came from a military background and had served as a captain of the dragoons of the Regiment of Spain immediately before being appointed governor. When he first sailed to Baja California as the new governor he brought with him 25 dragoons and 25 infantrymen in order to help him with his expulsion of

2640-487: The Jesuits and, eventually, the further exploration of the rest of California. His military background would prove very helpful during the expedition. By the late 1760s, the Spanish king and a handful of other European rulers began to realize the importance the Pacific coast of North America would have in maritime trade and activity. The Russians had been advancing south from their strongholds in present-day Alaska , and

2728-498: The Native Americans, indicating that they were committed to creating peaceful relationships with the native people. The long-term goal was to create settlements, introduce farming, and convert the inhabitants to Christianity, so peaceful coexistence was important during the expedition. The Portolà expedition was the first land-based exploration by Europeans of what is now California. The expedition's most notable discovery

2816-403: The Portolà party left San Diego. Following the same route they had taken the year before, they traveled five weeks with only two days of rest, arriving at Monterey Bay on May 24. They did not lose a single man or suffer any illnesses, except for an eye infection that afflicted Fages and Crespí. That afternoon, Portolà, Crespí and a guard walked over the hills to Point Pinos on the northern tip of

2904-501: The Portolà party. The party, driving a supply train and food animals, included 25 leather-jacket soldiers under sergeant José Francisco Ortega ; muleteers; artisans; and 44 Christian Indians from Baja California, acting as servants and interpreters to communicate with Indians along the way. This group traveled slower than the Rivera party. Serra, trekking much of the way on a broken-down mule, finally caught up with Portolà, De la Campa and

2992-527: The Portolà/Serra party arrived in San Diego in good health, with 163 mules loaded with supplies. Desiring to push the sea expedition north to Monterey – as Gálvez had instructed – Portolá offered captain Vicente Vila of the San Carlos 16 of his own men to work the ship on its voyage to Monterey. But Vila had lost all his ship's officers, his boatswain , coxswain of

3080-746: The Portolá Expedition. Camp Pendleton Marine Corps Base Camp Pendleton is the major West Coast base of the United States Marine Corps and is one of the largest Marine Corps bases in the United States. It is on the Southern California coast in San Diego County and is bordered by Oceanside to the south, San Clemente in Orange County to the north, Riverside County to

The commanding officers prepared to dispatch the San Antonio back to Lower California New Spain, to report to viceroy de Croix and visitador Gálvez about the expedition. On July 1, just as the ship was about to sail,

3256-471: The Santa Margarita River include the rainbow trout ( Oncorhynchus mykiss ), arroyo chub ( Gila orcuttii ), California killifish ( Fundulus parvipinnis ), striped mullet, longjaw mudsucker, staghorn sculpin. Pacific lamprey ( Entosphenus tridentatus ) recolonized the river in August 2019 for the first time since 1940, the furthest south the species has currently recolonized, 260 miles (420 km) south of

3344-601: The Santa Margarita area. After 1821, following the Mexican War of Independence from Spain, some of the former members of the Portolà expedition who had stayed on (mostly garrison soldiers) were awarded large land grants ( ranchos ) by Mexican governors. The retired soldiers were joined as rancheros by prominent businessmen, officials, and military leaders. They and their children, the Californios , became

3432-606: The TCA filed for permission to build on the northwestern portion of the base. A spokesman for Camp Pendleton denied the request in 2010, stating that they could only allow the toll road to run through the San Onofre State Beach Park because their training missions could not be completed without the proposed land. In fact, the California gnatcatcher , an endangered species , resides on the northwestern portion of

3520-513: The West Coast. Today it is home to myriad Operating Force units, including the I Marine Expeditionary Force and various training commands. In 1769, a Spanish expedition led by Captain Gaspar de Portolá explored northward from Loreto, Baja California Sur , seeking to reach Monterey Bay , something never before done overland by Europeans. On July 20 of that year , the expedition arrived in

The first leg of the expedition consisted of five groups all departing from Baja California and heading north for San Diego. Three groups traveled by sea while two others traveled by land in mule trains. Three galleons , hastily built in San Blas , set sail for San Diego in early 1769: the San Carlos , captained by Vicente Vila,

3696-463: The area now known as Camp Pendleton, and as it was the feast day of St. Margaret , they christened the land in the name of Santa Margarita. The expedition went on to establish military outposts and Franciscan missions at San Diego and Monterey . During the next 30 years, 21 missions were established, the most productive one being Mission San Luis Rey , just south of the present-day Camp Pendleton. At that time, San Luis Rey Mission had control over

3784-609: The base still includes breeding habitat for birds such as the western snowy plover and California gnatcatcher . The coastal bluffs have many of the few existing specimens of the Pendleton button-celery , which was named for the base. Rare mammals on the base include the Pacific pocket mouse and Stephens's kangaroo rat . Fourteen American bison were introduced from the San Diego Zoo between 1973 and 1979. They roam

3872-400: The base. The TCA funded a study in 2013 to remove the California gnatcatcher from the endangered species list, which would have made it easier to negotiate the construction and planning of the 241's extension through the San Onofre State Beach Park. Areas 11-16 are collectively known as "Mainside." Camp Pendleton was built on a wide swath of coastal land that once supported an estuary at

3960-421: The camp. The number of men engaged in those arduous labors diminished daily due to illness. Nearly all medicines and stored food had been consumed on the long voyages. Doctor Pedro Prat – himself weakened by scurvy – gathered medicinal herbs in the fields and desperately tried to cure the ill men. Heat scorched them by day, cold stung them by night. Two or three men died every day, until

4048-480: The combined sea expedition – which had started with over 90 men – had shrunk to eight soldiers and eight sailors. Captain Rivera 's column arrived on May 14, having trekked 300 miles (480 km) in 50 days from Velicatá without losing a single man or having a sick one – although with their food rations drastically reduced. Rivera's men moved the camp slightly inland near

4136-534: The confluence of Temecula Creek and Murrieta Creek , in southwestern Riverside County , east of Interstate 15 , 0.5 miles (0.80 km) southeast of Temecula . The river is formed when the two creeks merge. It flows southwest through the 5 miles (8.0 km) Temecula Canyon at the south end of the Santa Ana Mountains. Along its lower 10 miles (16 km) the river forms a large floodplain as it crosses Camp Pendleton Marine Corps Base . It enters

4224-541: The country's fighting force for the Korean and Vietnam Wars , approximately 200,000 Marines passed through the base on their way to the Far East. Beginning in 1954, Camp Pendleton has hosted a variation of Basic Training familiarization for teenagers age 14 to 17. This training, called "Devil Pups", promotes physical fitness, instills discipline and promotes love of country and the Marine Corps. The camp's stables display

4312-439: The deed to the ranch. During his tenure as owner, he expanded the ranch house, built in 1827, and developed the rancho into a thriving cattle industry. Forster's heirs were forced to sell the ranch in 1882 because of a series of droughts and a fence law that forced Forster to construct fencing around the extensive rancho lands. It was purchased by wealthy cattleman James Clair Flood and managed by Irishman Richard O'Neill, who

4400-464: The east side. However, they only got as far as present-day Hayward before turning back – because their allotted three days were up. When the scouts returned and described what they had seen, Portolà led the entire party up into the hills, to a place where the entire San Francisco Bay was visible . Only friar Crespí seemed to grasp the importance of the bay, describing it in his diary as "a very large and fine harbor, such that not only all

4488-502: The effects of scurvy . Portolà and his men continued north along the coast, hoping to find the great port they had now left behind. On October 30, they reached the headlands near today's Moss Beach . Looking into the Pacific Ocean, they could see the Farallon Islands due west – and Drakes Bay curving broadly to Point Reyes across 40 miles (65 km) of open water to the northwest. Drake's Bay had been named

4576-433: The four groups had reunited in San Diego, friars Juan Vizcaíno and Fernando Parrón stayed there with Junípero Serra to head the new mission San Diego . Friars Juan Crespí and Francisco Gómez continued north with Portolà. Serra's group aimed to establish Catholic missions to convert the natives of Alta California to Christianity. Crespí was the only one who traveled with the land expedition throughout its travels, so he became

4664-633: The friars held a Mass in honor of saint Joseph  – patron saint of the Portolá expedition – the Portolá party pulled out of San Diego. Serra stayed behind, as did captain Vicente Vila and the few sailors who remained on the San Carlos . Serra founded mission San Diego in a humble building just two days after the expedition's departure. While Portolà moved north, more men died in San Diego: Eight soldiers, four sailors, eight Christian Indians, and one servant perished by

4752-595: The future pueblo of Los Angeles . They continued moving northwest along a route that would become El Camino Real (royal path or road) in New Spain. On September 30, as the party camped by a river just south of today's Salinas , scouts ranged west to the coast. They reached Monterey Bay but failed to recognize it as the port described by Vizcaíno 167 years earlier. The rest of the party reached Monterey Bay on October 1 – but still failed to recognize it as their destination, because it did not seem to match

4840-444: The grand scale described by Vizcaíno. Also, Portolà and his hungry men had hoped to find the supply ship San José waiting for them at anchor in their destination harbor of Monterey. They never saw the San José , apparently lost at sea. Its morale waning, the party resumed its march on October 7, reaching the area of Espinosa Lake east of today's Castroville . By then, at least ten of the party were being carried on litters , due to

4928-423: The headwaters of the Santa Margarita River at the confluence of Temecula Creek and Murrieta Creek. Major riparian plants include arroyo, black, narrowleaf, Pacific, and red willow ( Salix spp ); California sycamore ( Platanus racemosa ), Fremont cottonwood ( Populus fremontii ), mulefat ( Baccharis salicifolia ) and White alder ( Alnus rhombifolia ). Portol%C3%A0 expedition The Portolá expedition

5016-505: The land groups. The San Carlos and San Antonio were followed by an additional supply ship, the San José , which was named after the patron saint of the Portolà expedition, Saint Joseph . The San José never reached San Diego and was presumed lost at sea. Captain Fernando Rivera , moving north through Baja California, gathered horses and mules from the fragile chain of Catholic missions to supply his overland expedition. José de Gálvez had ordered Rivera to requisition horses and mules from

5104-596: The landed gentry of Alta California . In 1841, two brothers, Pio Pico and Andrés Pico , became the first private owners of Rancho Santa Margarita. More land was later added to the grant, giving it the name of Rancho Santa Margarita y Las Flores , which stayed with the ranch until the Marine Corps acquired it in 1942. The design of the ranch's cattle brand is seen in the base's logo today. In 1863, an Englishman named John (Don Juan) Forster (Pio Pico's brother-in-law) paid off Pico's gambling debts in return for

5192-784: The last major undeveloped portion of the California coastline south of Santa Barbara , save for a few relatively small state parks. In 2015 the site was proposed for a large civilian airport. Since August 2004, Camp Pendleton has been one of five locations in the Department of Defense to operate the Standard Terminal Automation Replacement System (STARS) air radar. The STARS radar allows the facility to simulate air traffic for training purposes. Camp Pendleton's five-man color guard has participated in many sporting events in San Diego and at

5280-461: The launch and storekeeper – and none of the men offered by Portolà had experience as sailors. Vila refused to sail under such conditions. So Portolà decided to place all available sailors aboard the San Antonio , which set out for San Blas on July 9, with a very small crew. Carrying important letters from Serra, Portolà and others, the San Antonio reached San Blas in just three weeks. On that voyage, several more sailors died. After

5368-614: The lower mainstem has expansive riparian strips, some up to 1.5 kilometres (0.93 mi) across. Approximately 70 species of special concern (rare, threatened, or endangered) regularly inhabit the watershed, including 30 that are currently protected under the Endangered Species Act . Two federally endangered riparian birds are the least Bell's vireo ( Vireo bellii pusillus ) and the southwestern willow flycatcher ( Emmpidonax traillii extimus )), both of which require riparian habitat for breeding success.

Then, in 1767, Charles III of Spain expelled the Jesuit order from the Spanish kingdom. Gaspar de Portolà , a Catalan military officer and colonial administrator, was appointed governor of the new province of Las Californias and sent to dispossess

5544-584: The men waiting to board, declared their final destination as Monterey and their mission to plant the holy cross among the Indians. Friar Parrón boarded the San Carlos along with captain Vicente Vila, followed by lieutenant Pedro Fages with his 25 Catalan volunteers ; cartographer Miguel Costansó , who made maps and drawings to describe the journey; surgeon Pedro Prat; and a crew of 23 sailors, plus two blacksmiths, two boys, four cooks, and mate Jorge Estorace – a crew of 62 in all. Weighing anchor,

Friar Juan Crespí , selected as chaplain for the Rivera party and diarist for the Franciscan missionaries, traveled for 24 days from Mission La Purísima , approximately 400 miles (640 km) north to Velicatá, then

5720-656: The most part, it was reported that interactions with Native American tribes in Alta California were peaceful without much conflict. Many were described as welcoming and helpful, as they offered guidance and supplies to the Spanish explorers. Friendly encounters with the native people had been a goal from the onset of the expedition, and the Spanish brought many items and trinkets with which they traded for supplies and used to create peaceful relations. They used valuable space to carry so many glass beads and other items, rather than food or more crucial supplies, in order to pacify

5808-650: The mouth of the Santa Margarita River and extensive salt marsh habitat. Outlying land within the base is made up of floodplain , oak woodlands , coastal dunes and bluffs, coastal sage scrub , chaparral , and several types of wetlands, including ephemeral wetlands such as vernal pools . Wildfire is not uncommon. Research in ecology takes place on undeveloped areas of the base, which contain examples of rare and endangered California habitat types. The Department of Defense has issued management plans for various ecosystems on this territory. Land within

On November 11, Portolà convened an officers' council, which agreed unanimously that 1) they must have passed Monterey, 2) it was time to turn around and retrace their steps back to San Diego , and 3) no one would be left behind hoping for a supply ship to arrive. The entire party headed back south. On November 28,

By October 1944, Camp Pendleton was declared a "permanent installation," and by 1946 it became the home of the 1st Marine Division . It was named after Major General Joseph Henry Pendleton (1860–1942), who had long advocated setting up a training base for the Marine Corps on

6072-495: The northern frontier of Spanish settlement in Baja California. There Crespí met up with the Rivera party, which set out from Velicatá on March 24. Their mule and horse train, tended by three muleteers , carried 25 leather-jacket soldiers and 42 Baja California Christian Indians (all men). Portolà himself led the second land group, which set out from Loreto on March 9. Junípero Serra , assigned by José de Gálvez to head

6160-402: The nuclei of permanent settlements, established a cattle ranching economy and converted thousands of Native Americans to Christianity. Three diaries written by members of the expedition survive, giving unusually complete insight into the daily movements and experiences: One by Portolà himself, a record by Miguel Costansó , and a diary by Juan Crespí which is the most complete and detailed of

6248-506: The official diarist for the missionaries (Portolà and Costansó also kept diaries). The Franciscans ultimately founded twenty-one missions at or near the Pacific Coast of what is now the state of California, in addition to one mission in Baja California. The string of California missions began at San Diego. After two weeks of recuperation, Portolà resumed the northward march to rediscover Vizcaíno 's port of Monterey by land, with

6336-776: The other members of their party on May 5, just south of Velicatá. Following the trail blazed by the Rivera party, and less burdened by livestock, the Portolà party moved somewhat faster. Even so, they had an arduous trek over deserts and through ravines. The ships arrived in San Diego first: the San Antonio on April 11 and the San Carlos on April 29, 1769. Many crew members on both ships had fallen ill – especially from scurvy  – during their voyages. On May 1, lieutenant Pedro Fages , engineer Miguel Costansó , and mate Jorge Estorace came ashore from their anchorage in San Diego Bay , along with 25 soldiers and sailors still healthy enough to work. Searching for

6424-527: The party crossed the Monterey Peninsula south to Carmel Bay . A week later, while waiting for two Baja Christian Indians who got separated from Rivera 's group, the expedition leaders discussed their next moves. They still did not believe they had found Vizcaíno 's port of Monterey. On December 7, they decided to return to San Diego without waiting any longer for the missing men, or for a supply ship. On December 10, Portolà ordered his men to plant

6512-559: The party had survived their six-month journey. They told of large numbers of friendly Indians who lived along the coast, waiting to receive the Catholic gospel. In total they had traveled around 1,200 miles (1,900 km) and become the first Europeans to survey San Francisco Bay and many other important strategic locations. Yet friar Junípero Serra , who welcomed them back to San Diego, felt dismayed and incredulous that they had not found Monterey Bay. "You come from Rome without having seen

6600-552: The pope", Serra told Portolà. A second expedition to find Monterey Bay and establish a permanent settlement there took place in 1770. Portolà mustered a new overland party in San Diego, consisting of less than half the number of men he had taken on his first trip to find Monterey. The new party included Pedro Fages with twelve Catalan volunteers , seven leather-jacket soldiers, two muleteers , five Baja Christian Indians, Portolà's servant, and friar Crespí . Rivera had traveled back to Baja California to get supplies. On April 17,

6688-481: The previous location in San Luis Obispo which recolonized in 2017. The successful recolonization has been attributed to a rebuilt weir and new fishway at Camp Pendleton which allowed the lamprey to find passage into the river. Aquatic and semi-aquatic mammals include California golden beaver ( Castor canadensis subauratus ), muskrat, raccoon and long-tailed weasel. Contemporary beaver populations survive at

6776-744: The right. The two latter creeks drain the Santa Rosa Plateau . Approximately 4,334 acres (1,754 ha) of the middle course of the Santa Margarita River in Temecula Canyon are managed by San Diego State University as the Santa Margarita Ecological Reserve , a collaboration of the Bureau of Land Management , California Department of Fish and Wildlife and The Nature Conservancy . The Nature Conservancy has identified and continues to acquire land along

6864-546: The river for conservation. Downstream from the Ecological Preserve the river flows through lands owned by the Fallbrook Public Utility District , and empties into the Ocean through the largely undisturbed lands of Camp Pendleton . Thus the mainstem flows through undeveloped, protected lands. The river has unusual habitats with the upper mainstem one of the few remaining natural gorge rivers in Southern California and

6952-461: The river. While it was operating, Chinese Americans worked on the railroad. The route along the river was abandoned in 1891. In the early 20th century, following a lawsuit against Vail Ranch in Temecula , water was guaranteed for the river to continue to flow. During much of the 20th century, and into the early 21st century, the river was the subject of a long-running water rights battle between

7040-529: The solidification of Spanish territorial claims in the disputed and unexplored regions along the Pacific coast of North America. Although already inhabited by Native Americans, the territory that is now California was claimed by the Spanish Empire in 1542 by right of discovery when Juan Rodríguez Cabrillo explored the Pacific coast . Cabrillo's exploration laid claim to the coastline as far north as forty-two degrees north latitude. This northern limit

7128-440: The three. When Portolà returned to New Spain in 1770, Pedro Fages (now promoted to captain) was appointed lieutenant governor of Alta California, with headquarters at the Presidio of Monterey . Fages led further exploratory trips to the east side of San Francisco Bay, and left his own diaries. California Historical Landmarks #2, 21, 22, 23, 24, 25, 26, 27, 92, 94, 375, 394, 655, 665, 727, 784, 1058, and 1059 are all related to

7216-543: The time the Portolà party returned six months later. On July 28, the Portolà party reached a major southern California river, which the soldiers called the Santa Ana River . That afternoon they felt a strong earthquake , with aftershocks jolting them over the next few days. On August 2 they traveled west out of San Gabriel Valley , through the hills to a river Crespí named El Río de Nuestra Señora la Reina de los Ángeles de Porciúncula  – site of

7304-468: The upper watershed, both dams must release water that roughly corresponds to natural flows in the tributaries that they are on. As a result, the flow of water in the Santa Margarita River is very close to what it would be in the absence of those two dams. Below the confluence of Murrieta and Temecula Creeks, the primary tributaries of the Santa Margarita River mainstem are Rainbow Creek on the left (headingdownstream) and Sandia Creek and De Luz Creeks on

7392-565: The wooden cross left on a hill the year before, and this time (perhaps on a clearer day) realized that the site did indeed overlook the place Vizcaíno had described. Portolà founded the Presidio of Monterey on that hill, and Serra founded the Mission San Carlos Borromeo (moved to Carmel the next year, a little ways to the south). On July 9, 1770, Portolà and Costansó boarded the San Antonio and sailed out of Monterey Bay, headed back to Baja California New Spain. For

7480-489: Was San Francisco Bay, but nearly every stop along the route was a first. It is also important in that it, along with the later de Anza expedition , established the overland route north to San Francisco which became the Camino Real . That route was integral to the settlement of Alta California by the Spanish Empire, and made it possible for the Franciscan friars to establish a string of twenty-one missions , which served as

7568-425: Was a Spanish voyage of exploration in 1769–1770 that was the first recorded European exploration of the interior of the present-day California. It was led by Gaspar de Portolá , governor of Las Californias , the Spanish colonial province that included California, Baja California , and other parts of present-day Mexico and the United States. The expedition led to the founding of Alta California and contributed to

7656-523: Was eventually rewarded for his faithful service with half ownership. Under the guidance of O'Neill's son, Jerome, the ranch made a profit of nearly half a million dollars annually, and the house was modernized and refurbished. In the early 1940s, both the Army and the Marine Corps were looking for land for a large training base. The Army lost interest in the project, but in February 1942 it was announced that

7744-518: Was later confirmed by the United States in the 1819 Adams–Onís Treaty . A competing claim was established for England in 1579 by the privateer Francis Drake , who followed the trans-Pacific route from the Philippines established by the Manila galleons and reached the California coast near Cape Mendocino , from which he then sailed south along the coast at least as far as Point Reyes . In 1596,
