Hydroelectric power , food, and lumber provided by Oregon helped fuel the development of
6003-444: The past 1,800 years from vents high on the southwest flank and produced deposits that were distributed primarily to the south and west along the Sandy and Zigzag rivers. The volcano has had a VEI of 2 at least three times before. The last eruptive period took place around 220 to 170 years ago, when dacitic lava domes, pyroclastic flows and mudflows were produced without major explosive eruptions. The prominent Crater Rock just below
6090-410: The region after the law was passed were forced to leave, and those who did not comply were arrested and beaten. They received no less than twenty and no more than thirty-nine stripes across the back if they still did not leave. This process could be repeated every six months. Slavery played a major part in Oregon's history and even influenced its path to statehood. The territory's request for statehood
6177-519: The region west of the Rocky Mountains to the Pacific Ocean. By the 1820s and 1830s, the Hudson's Bay Company dominated the Pacific Northwest from its Columbia District headquarters at Fort Vancouver (built in 1825 by the district's chief factor, John McLoughlin , across the Columbia from present-day Portland ). In 1841, the expert trapper and entrepreneur Ewing Young died leaving considerable wealth and no apparent heir, and no system to probate his estate. A meeting followed Young's funeral, at which
6264-489: The round topped mountain, which we saw a short distance below the banks of the river, is South 43-degrees West of us and about 37 mi (60 km). It is at this time topped with snow. We called this the Falls Mountain, or Timm Mountain." Timm was the native name for Celilo Falls. Clark later noted that it was also Vancouver's Mount Hood. Two French explorers from the Hudson's Bay Company may have traveled into
6351-935: The shortest being a small walk from the Timberline Lodge. A portion of the Pacific Crest Trail is coincident with the Timberline Trail on the west side of Mount Hood. The predecessor of the Pacific Crest Trail was the Oregon Skyline Trail , established in 1920, which connected Mount Hood to Crater Lake . Mount Hood is Oregon's highest point and a prominent landmark visible up to 100 mi (160 km) away. About 10,000 people attempt to climb Mount Hood each year. It has convenient access, though it presents some technical climbing challenges. There are no trails to
6438-548: The south route, begins at Timberline Lodge and proceeds up Palmer Glacier to Crater Rock, the large prominence at the head of the glacier. The route goes east around Crater Rock and crosses the Coalman Glacier on the Hogsback, a ridge spanning from Crater Rock to the approach to the summit. The Hogsback terminates at a bergschrund where the Coalman Glacier separates from the summit rock headwall . The route continues to
6525-591: The southern boundary with California and Nevada . The western boundary is formed by the Pacific Ocean . Oregon has been home to many indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early to mid-16th century. As early as 1564, the Spanish began sending vessels northeast from the Philippines , riding
6612-463: The southern flank of Mount Hood just below Palmer Glacier , with an elevation of about 6,000 ft (1,800 m). The mountain has four ski areas : Timberline , Mount Hood Meadows , Ski Bowl , and Cooper Spur . They total over 4,600 acres (7.2 sq mi; 19 km ) of skiable terrain; Timberline, with one lift having a base at nearly 6,940 ft (2,120 m), offers the only year-round lift-served skiing in North America. There are
6699-421: The state's name is uncertain. The earliest geographical designation "orejón" (meaning "big ear") comes from the Spanish historical chronicle Relación de la Alta y Baja California (1598), written by Rodrigo Montezuma of New Spain ; here it refers to the region of the Columbia River as it was encountered by the first Spanish scouts. The " j " in the Spanish phrase " El Orejón " was eventually corrupted into
6786-484: The summit is hypothesized to be the remains of one of these now-eroded domes. This period includes the last major eruption of 1781 to 1782 with a slightly more recent episode ending shortly before the arrival of the explorers Lewis and Clark in 1805. The latest minor eruptive event was thought to have occurred in August 1907, but has been discredited as "an observation of non-eruptive fumarolic activity." The glaciers on
6873-509: The summit, with even the "easier" southside climbing route constituting a technical climb with crevasses, falling rocks, and often inclement weather. Ropes, ice axes , crampons and other technical mountaineering gear are necessary. Peak climbing season is generally from April to mid-June. There are six main routes to approach the mountain, with about 30 total variations for summiting. The climbs range in difficulty from class 2 to class 5.9+ (for Acrophobia ). The most popular route, dubbed
6960-461: The summit. The retreat released considerable outwash, some of which filled and flattened the upper Hood River Valley near Parkdale and formed Dee Flat . Older glaciation produced moraines near Brightwood and distinctive cuts on the southeast side; they may date to 140,000 years ago. Mt. Hood National Forest is home to approximately 1,000 mi (1,600 km) of trails. Cooper Spur Trail leads to 8,510 ft (2,590 m) in elevation,
7047-459: The years, as seen in the following table: Early explorers on the Columbia River estimated the elevation to be 10,000 to 12,000 ft (3,000 to 3,700 m). Two people in Thomas J. Dryer's 1854 expedition calculated the elevation to be 18,361 ft (5,596 m) and the tree line to be at 11,250 ft (3,430 m). Two months later, a Mr. Belden claimed to have climbed the mountain during
7134-724: Was applied to the River of the West based on Native American tales of powerful Chinook winds on the lower Columbia River, or perhaps from first-hand French experience with the Chinook winds of the Great Plains . At the time, the River of the West was thought to rise in western Minnesota and flow west through the Great Plains. Another suggestion comes from Joaquin Miller , who wrote in Sunset magazine in 1904: The name, Oregon,
7221-498: Was commissioned in May 1971 and decommissioned in August 1999. The glacially eroded summit area consists of several andesitic or dacitic lava domes ; Pleistocene collapses produced avalanches and lahars (rapidly moving mudflows) that traveled across the Columbia River to the north. The eroded volcano has had at least four major eruptive periods during the past 15,000 years. The last three eruptions at Mount Hood occurred within
7308-574: Was delayed several times, as members of Congress argued among themselves whether the territory should be admitted as a "free" or "slave" state. Eventually politicians from the South agreed to allow Oregon to enter as a "free" state, in exchange for opening slavery to the Southwestern U.S. Oregon was admitted to the Union on February 14, 1859, though no one in Oregon knew it until March 15. Founded as
7395-442: Was first seen by European explorers in 1792 and is believed to have maintained a consistent summit elevation, varying by no more than a few feet due to mild seismic activity. Elevation changes since the 1950s are predominantly due to improved survey methods and model refinements of the shape of the Earth (see vertical reference datum ). Despite the physical consistency, the estimated elevation of Mount Hood has varied substantially over
7482-545: Was formed in the Oregon Country , and the Oregon Territory was created in 1848. Oregon became the 33rd state of the U.S. on February 14, 1859. Today, with 4.2 million people over 98,000 square miles (250,000 km ), Oregon is the ninth largest and 27th most populous U.S. state. The capital, Salem , is the third-most populous city in Oregon, with 175,535 residents. Portland , with 652,503, ranks as
7569-438: Was the first acting public government of the Oregon Country before annexation by the government of the United States. It was succeeded by a Second Executive Committee, made up of Peter G. Stewart , Osborne Russell , and William J. Bailey , and this committee was itself succeeded by George Abernethy , who was the first and only Governor of Oregon under the provisional government. Also in 1841, Sir George Simpson , governor of
