51-735: The Grand Staircase–Escalante National Monument (GSENM) is a United States national monument protecting the Grand Staircase , the Kaiparowits Plateau , and the Canyons of the Escalante ( Escalante River ) in southern Utah . It was established in 1996 by President Bill Clinton under the authority of the Antiquities Act with 1.7 million acres of land, later expanded to 1,880,461 acres (7,610 km). In 2017,

102-478: A donation of lands acquired by John D. Rockefeller Jr. , for addition to Grand Teton National Park after Congress had declined to authorize this park expansion. Roosevelt's proclamation unleashed a storm of criticism about use of the Antiquities Act to circumvent Congress. A bill abolishing Jackson Hole National Monument passed Congress but was vetoed by Roosevelt, and Congressional and court challenges to

153-837: A fifth in the Atlantic Ocean, the Northeast Canyons and Seamounts Marine National Monument . On June 24, 2016, Obama designated the Stonewall Inn and surrounding areas in Greenwich Village , New York as the Stonewall National Monument , the first national monument commemorating the movement for LGBT rights in the United States . Obama's establishments included several others recognizing civil rights history, including

204-641: A group of cavalry to the headwaters of the Escalante River. In 1871 Jacob Hamblin of Kanab , on his way to resupply the second John Wesley Powell expedition, mistook the Escalante River for the Dirty Devil River and became the first Anglo to travel the length of the canyon. In 1879 the San Juan Expedition crossed through the region on their way to a proposed Mormon colony in the far southeastern corner of Utah. Traveling on

255-477: A largely unexplored route, the group eventually arrived at the 1,200-foot (370 m) sandstone cliffs that surrounded Glen Canyon . They found the only breach for many miles in the otherwise vertical cliffs, which they named Hole-in-the-Rock . The narrow, steep, and rocky crevice eventually led to a steep sandy slope in the lower section and eventually down to the Colorado River . With winter settling in,

306-477: A major Alaska lands bill. Congress passed a revised version of the bill in 1980 incorporating most of these national monuments into national parks and preserves , but the act also curtailed further use of the proclamation authority in Alaska. Carter's 1978 proclamations included Misty Fjords and Admiralty Island National Monuments in the U.S. Forest Service and Becharof and Yukon Flats National Monuments in

357-642: A monument also nixed the Andalex Coal Mine that was proposed for a remote location on the Kaiparowits Plateau. Wilderness designation for the lands in the monument had long been sought by environmental groups; however, the designation of a monument is not the same as wilderness designation, as activities such as motorized vehicle and mountain bike use are allowed in National Monuments. There are contentious issues peculiar to

408-525: A precedent for the use of the Antiquities Act to preserve large areas. Federal courts have since rejected every challenge to the president's use of Antiquities Act preservation authority, ruling that the law gives the president exclusive discretion over the determination of the size and nature of the objects protected. In 1918, President Woodrow Wilson proclaimed Katmai National Monument in Alaska , comprising more than 1,000,000 acres (4,000 km ). Katmai

510-529: Is dominated by a single long ridge, called the Kaiparowits Plateau from the west, and Fifty-Mile Mountain when viewed from the east. Fifty-Mile Mountain stretches southeast from the town of Escalante to the Colorado River in Glen Canyon . The eastern face of the mountain is a 2,200 ft (670 m) escarpment . The western side (the Kaiparowits Plateau) is a shallow slope descending to

561-625: Is hereby granted." The statute was repealed by the Federal Land Policy and Management Act (FLPMA) of 1976, but the repeal was subject to valid existing rights. A process for resolving disputed claims has not been established, and in 1996, the 104th United States Congress passed a law that prohibited the R.S. 2477 (proposed resolution regulations) written by the Clinton Administration from taking effect without congressional approval. The right to maintain and improve

663-557: Is today. It is extremely fossil rich, with thousands of plants and animal fossils being preserved in amongst its sandstone and mudstone deposits. Based on plants remains including multiple vines, leaves, and branches, It was assumed by paleontologists Scott Sampson and his colleagues that Utah in the Campanian was a dense jungle bordering the Western Interior Seaway . The jungle theory would also support why almost all

714-767: The Bureau of Land Management , and the National Oceanic and Atmospheric Administration (in the case of marine national monuments). Historically, some national monuments were managed by the War Department . President Theodore Roosevelt used the Antiquities Act to declare Devils Tower in Wyoming as the first U.S. national monument. The Antiquities Act authorized permits for legitimate archaeological investigations and penalties for taking or destroying antiquities without permission. Additionally, it authorized

765-580: The César E. Chávez , Belmont–Paul Women's Equality , Freedom Riders , and Birmingham Civil Rights National Monuments . In December 2017, President Donald Trump substantially reduced the sizes of Bears Ears and Grand Staircase–Escalante National Monuments , removing protections on about 2.8 million acres of land where mining could resume. Three lawsuits challenged the legality of this action in federal court, and in October 2021, President Joe Biden reversed

816-662: The Fish and Wildlife Service , the first to be created outside of the National Park Service. The latter two became national wildlife refuges in 1980. The proclamation authority was not used again anywhere until 1996, when President Bill Clinton proclaimed the Grand Staircase–Escalante National Monument in Utah , after many years of unsuccessful advocacy by conservationists to protect parts of

867-655: The Grand Canyon as a national monument. In response to Roosevelt's declaration of the Grand Canyon monument, a putative mining claimant sued in federal court, claiming that Roosevelt had overstepped the Antiquities Act authority by protecting an entire canyon. In 1920, the United States Supreme Court ruled unanimously that the Grand Canyon was indeed "an object of historic or scientific interest" and could be protected by proclamation, setting

918-492: The United States , a national monument is a protected area that can be created from any land owned or controlled by the federal government by proclamation of the president of the United States or an act of Congress. National monuments protect a wide variety of natural and historic resources, including sites of geologic, marine, archaeological, and cultural importance. The Antiquities Act of 1906 gives presidents

969-536: The duckbill Parasaurolophus cyrtocristatus , and a variety of early mammals including multituberculates , marsupials , and insectivorans . Recent finds include large specimens of the duckbill Gryposaurus , including the species G. monumentensis , and the first described remains of the oviraptorosaurian Hagryphus giganteus . Trace fossils are also known from the Kaiparowits, including an excellently preserved hadrosaur skin impression known from

1020-530: The volcaniclastic Upper Valley Member estimated to date from 73.8 to 72.8 million years ago. The timeline below follows the re-calibrated timeline of Fowler (2017), showing species from the Kaiparowits Formation in green, and related species from Alberta in blue. The Kaiparowits Formation is a muddy bed that was deposited between about 77.3 to 72.8 million years ago, in the area where the Grand Staircase–Escalante National Monument of Utah

1071-560: The American West. The reference in the act to "objects of ... scientific interest" enabled President Theodore Roosevelt to make a natural geological feature, Devils Tower in Wyoming , the first national monument three months later. Among the next three monuments he proclaimed in 1906 was Petrified Forest in Arizona , another natural feature. In 1908, Roosevelt used the act to proclaim more than 800,000 acres (3,200 km ) of

1122-563: The BLM. Visitor centers are located in Cannonville , Big Water , Escalante , and Kanab . The monument stretches from the towns of Big Water , Glendale , and Kanab, Utah in the southwest to the towns of Escalante and Boulder in the northeast. The monument is slightly larger in area than the state of Delaware . After a reduction ordered by presidential proclamation in December 2017,

1173-643: The Fremont hunted and gathered below the plateau and near the Escalante Valley, and the ancestral Puebloans farmed in the canyons. Both groups grew corn, beans, and squash, built brush-roofed pithouses, and took advantage of natural rock shelters. Ruins and rock art can be found throughout the Monument. The first record of white settlers in the region dates from 1866 when Captain James Andrus led

1224-996: The Pacific Ocean, the largest in the system: the Papahānaumokuākea Marine National Monument , the Pacific Remote Islands Marine National Monument , the Marianas Marine National Monument , and the Rose Atoll Marine National Monument . They are managed by the Fish and Wildlife Service, with the National Oceanic and Atmospheric Administration overseeing the fisheries. President Barack Obama significantly expanded two of them and added

1275-475: The Utah Schools and Lands Exchange Act of 1998, supported by Democrats and Republicans, and signed into law as Public Law 105–335 on October 31, 1998. A more difficult problem is the resolution of United States Revised statute 2477 (R.S. 2477) road claims. R.S. 2477 (Section 8 of the 1866 Mining Act) states: "The right-of-way for the construction of highways over public lands, not reserved for public uses,

1326-704: The animals in the Kaiparowits Formation were new species, and why the deposits were so plentiful. Without the need for herbivores to migrate to find food, and theropods to migrate after herbivores, a whole ecosystem could evolve secluded from interbreeding. The theory also supported why the dinosaurs adorned such features like the 15 horns of Kosmoceratops , they were for sexual selection . Animals present include chondrichthyans (sharks and rays), gars , bowfin , sturgeons , frogs , salamanders , turtles , lizards , crocodilians (including Deinosuchus ), coelurosaurian theropods such as dromaeosaurids , troodontids , and Ornithomimus velox , armored dinosaurs ,

1377-704: The area. This was the first national monument managed by the Bureau of Land Management . This action was unpopular in Utah, and bills were introduced to further restrict the president's authority, none of which have been enacted. Most of the 16 national monuments created by President Clinton are managed not by the National Park Service, but by the Bureau of Land Management as part of the National Landscape Conservation System . President George W. Bush created four marine national monuments in

1428-581: The base of Fifty-Mile Mountain. The Dry Fork Slots of Coyote Gulch and lower Coyote Gulch are also located off the Hole-in-the-Rock Road. Since 2000, numerous dinosaur fossils over 75 million years old have been found at Grand Staircase–Escalante. In 2002, a volunteer at the Monument discovered a 75-million-year-old dinosaur near the Arizona border. On October 3, 2007, the dinosaur's name, Gryposaurus monumentensis (hook-beaked lizard from

1479-414: The changes. The restoration of the monuments has been challenged in court in an attempt to attack the Antiquities Act. President Biden's proclamations establishing and expanding monuments often incorporated consultation with Native American tribes for management and planning. Kaiparowits Formation Traditionally, the Kaiparowits Formation has been considered to be roughly equivalent in age to

1530-420: The company decided to go down the crevice rather than retreat. After six weeks of labor, including excavation and using explosives to shift rock, they rigged a pulley system to lower their wagons and animals down the resulting road and off the cliff. There they built a ferry, crossed the river, and climbed back out through Cottonwood Canyon on the other side. A national monument was initially proposed in 1934, but

1581-402: The designation of the national monument, questioning whether the Antiquities Act allowed such vast amounts of land to be designated. However, United States Supreme Court decisions have long established the president's discretion to protect land under the Antiquities Act, and several lawsuits filed in an effort to overturn the designation were dismissed by federal courts. The area's designation as

1632-634: The discovery of a new species, Lythronax argestes , was announced. It is a tyrannosaur that is approximately 13 million years older than Tyrannosaurus , named for its great resemblance to its descendant. The specimen can be seen at the Natural History Museum of Utah. Humans did not settle permanently in the area until the Basketmaker III Era , around AD 500. Both the Fremont and ancestral Puebloan people lived here;

1683-463: The largest native turtle at about 78 centimeters in length. Helopanoplia indt. A softshell turtle Bernissartia May not be Bernissartia proper, but a close cousin. It would extend the family's time range to the Campanian. Alligatoroid Is similar in form to Allognathosuchus . Brachychampsa A new species yet to be described. Reached around 2 meters in length and

1734-470: The many unpaved roads in the national monument is disputed, with county officials placing county road signs on the roads they claim and occasionally applying bulldozers to grade claimed roads, while the Bureau of Land Management tries to exert control over the same roads. Litigation between the state and federal government over R.S. 2477 and road maintenance in the national monument is an ongoing issue. On December 4, 2017, President Donald Trump ordered that

1785-618: The monument encompassed 1,003,863 acres (4,062 km), but it was restored to 1,870,000 acres (7,568 km) in 2021. The western part of the monument is dominated by the Paunsaugunt Plateau and the Paria River , and is adjacent to Bryce Canyon National Park . This section shows the geologic progression of the Grand Staircase . Features include the slot canyons of Bull Valley Gorge, Willis Creek , and Lick Wash which are accessed from Skutumpah Road. The center section

1836-400: The monument's size be reduced by nearly 47% to 1,003,863 acres (4,062 km), with the remainder divided into three areas, two of which border one another along the Paria River . Bears Ears National Monument was significantly reduced in size at the same time. Conservation, angling, hunting, and outdoor recreation groups filed suit to block any reduction in the national monument, arguing that

1887-512: The monument's size was reduced by half in a succeeding presidential proclamation , and it was restored in 2021. The land is among the most remote in the country; it was the last to be mapped in the contiguous United States . The monument is administered by the Bureau of Land Management (BLM) as part of the National Conservation Lands system. Grand Staircase–Escalante is the first and largest national monument managed by

1938-747: The monument) was announced in the Zoological Journal of the Linnean Society . G. monumentensis was at least 30 feet (9.1 m) long and 10 feet (3.0 m) tall, and has a powerful jaw with more than 800 teeth. Many of the specimens from the Kaiparowits Formation are reposited at the Natural History Museum of Utah in Salt Lake City . Two ceratopsid (horned) dinosaurs, also discovered at

1989-713: The monument, were introduced by the Utah Geological Survey in 2007. They were uncovered in the Wahweap Formation , which is just below the Kaiparowits formation, where the duckbill was extracted. They lived about 80 million or 81 million years ago. The two fossils are called the Last Chance skull and the Nipple Butte skull. They were found in 2002 and 2001, respectively. Both were later identified as belonging to Diabloceratops . In 2013

2040-403: The northern Dinosaur Park Formation . This, combined with the differences in fauna between the two formations, has led some scientists, most notably Scott Sampson, to conclude that there was some barrier separating northern and southern Laramidia at this time. However, preliminary re-calibration of late Cretaceous formation correlations suggests that the upper part of the Kaiparowits, where many of

2091-434: The original boundaries. Two lawsuits, Garfield County v. Biden , filed by the state of Utah and two Utah counties, and Dalton v. Biden, filed by a mining company and recreationalists, seek to overturn the reaffirmed original boundaries and attack the Antiquities Act . The tribes filed motions to intervene. On August 11, 2023, U.S. District Judge David Nuffer dismissed both cases, explaining that "the Antiquities Act gives

2142-531: The power to proclaim national monuments by executive action. In contrast, national parks in the U.S. must be created by Congressional legislation. Some national monuments were first created by presidential action and later designated as national parks by congressional approval. The 134 national monuments are managed by several federal agencies: the National Park Service , United States Forest Service , United States Fish and Wildlife Service ,

2193-596: The president broad authority to designate national monuments and that courts cannot second-guess that authority." The state of Utah and other parties have since appealed the dismissal, but no such challenge has been successful in 100 years of the Antiquity Act's history. The United States Court of Appeals for the Tenth Circuit heard the case in September 2024. United States national monument In

2244-545: The president has no legal authority to materially shrink a national monument. The cases were still pending at the 2020 election . The Trump administration subsequently approved logging within the national monument and coal mining in the area that was removed from the monument. On his first day in office, President Joe Biden signed an executive order calling for a review of the reduction of the Bears Ears and Grand Staircase–Escalante monuments. On October 8, 2021, he restored

2295-940: The president to proclaim "historic landmarks, historic and prehistoric structures, and other objects of historic or scientific interest" on federal lands as national monuments, "the limits of which in all cases shall be confined to the smallest area compatible with the proper care and management of the objects to be protected." Presidents have used the Antiquities Act's proclamation authority not only to create new national monuments but to enlarge existing ones. For example, Franklin D. Roosevelt significantly enlarged Dinosaur National Monument in 1938. Lyndon B. Johnson added Ellis Island to Statue of Liberty National Monument in 1965, and Jimmy Carter made major additions to Glacier Bay and Katmai National Monuments in 1978. The Antiquities Act of 1906 resulted from concerns about protecting mostly prehistoric Native American ruins and artifacts (collectively termed "antiquities") on federal lands in

2346-512: The proclamation authority were mounted. In 1950, Congress finally incorporated most of the monument into Grand Teton National Park, but the act doing so barred further use of the proclamation authority in Wyoming except for areas of 5,000 acres or less. The most substantial use of the proclamation authority came in 1978, when President Jimmy Carter proclaimed 17 new national monuments in Alaska after Congress had adjourned without passing

2397-456: The project floundered until several decades later. It was on September 18, 1996, at the height of the 1996 presidential election campaign by President Bill Clinton , that the national monument was declared and was controversial from the moment of creation. The declaration ceremony was held at Grand Canyon National Park in Arizona , rather than in Utah. Local officials such as Democratic U.S. Representative Bill Orton from Utah objected to

2448-585: The south and west. East of Fifty-Mile Mountain is the Canyons of the Escalante . The monument is bounded by Glen Canyon National Recreation Area on the east and south. The popular hiking, backpacking, and canyoneering areas include Calf Creek Falls off Utah Scenic Byway 12 , and Zebra Canyon, Harris Wash , and the Devils Garden . The latter areas are accessed via the Hole-in-the-Rock Road , which extends southeast from Escalante, near

2499-470: The state of Utah. Certain plots of land were assigned when Utah became a state (in 1896) as School and Institutional Trust Lands (SITLa, a Utah state agency), to be managed to produce funds for the state school system. These lands included scattered plots in the monument that could no longer be developed. The SITLa plots within the monument were exchanged for federal lands elsewhere in Utah, plus equivalent mineral rights and $ 50 million cash by an act of Congress,

2550-521: The unique species are found, is actually younger than the Dinosaur Park, and that some Kaiparowits species may simply be the descendants of Dinosaur Park species. However, new dates reveal that this is simply an artifact of inaccurate Ar-Ar dating , and both formations had similar ages. According to new Uranium-Lead stratigraphic data, the fossil-bearing portion of the Kaiparowits Formation dates from about 77.24 to 75.02 million years ago, with

2601-550: Was later enlarged to nearly 2,800,000 acres (11,000 km ) by subsequent Antiquities Act proclamations and for many years was the largest national park system unit. Petrified Forest , Grand Canyon , and Great Sand Dunes , among several other national parks , were also originally proclaimed as national monuments and later designated national parks by Congress. Substantial opposition did not materialize until 1943, when President Franklin D. Roosevelt proclaimed Jackson Hole National Monument in Wyoming . He did this to accept
