Yellowstone National Park

The Gibbon River flows east of the Continental Divide in Yellowstone National Park, in northwestern Wyoming, the Northwestern United States. Along with the Firehole River, it is a major tributary of the Madison River, which itself is a tributary of the Missouri River.

The Canyon Hotel was built in Yellowstone National Park in 1910 by the Yellowstone Park Company to accommodate visitors to the area of the Grand Canyon of the Yellowstone and Yellowstone Falls. The hotel was built on a huge scale, with a perimeter measurement of one mile. Situated on a hill to the west of the falls, it dominated the landscape. It had an elegant resort-like air when first built. After World War II it was regarded by the National Park Service as outdated. Suffering from neglect, it was abandoned in the late 1950s and was in the process of demolition when it was destroyed by fire in 1960.

The Canyon Village Lodge at Yellowstone National Park is the largest single lodging property in Yellowstone National Park. Its renovation, first envisioned in 1988 as part of the Canyon Redevelopment Plan, is part of a larger undertaking to improve the dining and lodging prospectus park-wide.

Slough Creek is a tributary of the Lamar River, approximately 25 mi (40 km) long, in Montana and Wyoming in the United States.

The Lamar River is a tributary of the Yellowstone River, approximately 40 miles (64 km) long, in northwestern Wyoming in the United States. The river is located entirely within Yellowstone National Park.

Mammoth Hot Springs is a large complex of hot springs on a hill of travertine in Yellowstone National Park adjacent to Fort Yellowstone and the Mammoth Hot Springs Historic District. It was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate (over two tons flow into Mammoth each day in a solution). Because of the huge amount of geothermal vents, travertine flourishes. Although these springs lie outside the caldera boundary, their energy has been attributed to the same magmatic system that fuels other Yellowstone geothermal areas.

The Gallatin Range is a mountain range of the Rocky Mountains, located in the U.S. states of Montana and Wyoming. It includes more than 10 mountains over 10,000 feet (3,000 m). The highest peak in the range is Electric Peak at 10,969 feet (3,343 m).

The North Entrance Road Historic District is a historic district and road in Yellowstone National Park in Park County, Wyoming, and Park County, Montana in the United States, that is listed on the National Register of Historic Places (NRHP).

The Gardner River (also known as the Gardiner River) is a tributary of the Yellowstone River, approximately 25 miles (40 km) long, in northwestern Wyoming and south central Montana in the United States. The entire river is located within Yellowstone National Park. It rises on the slope of Joseph Peak, Gallatin Range in the northwestern part of the park, and winds southeast through Gardner's Hole, a broad subalpine basin which is a popular trout fishing location. The Gardner falls within the Native Trout Conservation Area and anglers are allowed to take an unlimited number of brown and rainbow trout. Mountain whitefish and Yellowstone cutthroat trout must be released. Angling on the Gardner is governed by Yellowstone National Park fishing regulations. After merging with Panther Creek, Indian Creek and Obsidian Creek, it then turns north and flows through a steep canyon where it cuts through a basaltic flow from approximately 500,000 years ago known as Sheepeater Cliffs. Below Sheepeater, Glen Creek out of Golden Gate Canyon and Lava Creek out of Lava Creek Canyon join the Gardner near Mammoth Hot Springs. The river crosses the 45th parallel in Gardner Canyon and is also home to a popular hot spring known as The Boiling River. The river continues north through Gardner Canyon and empties into the Yellowstone near Gardiner, Montana.

Golden Gate Canyon is in the northwestern region of Yellowstone National Park in the U.S. state of Wyoming. Glen Creek flows north through the canyon en route to the Gardner River descending from 7,400 feet (2,300 m) at Kingman Pass to just under 6,000 feet (1,800 m) in less than 3 miles (4.8 km). The northern portion of the Grand Loop Road traverses the canyon, connecting Mammoth Hot Springs with park features to the south.

Mammoth is a census-designated place in Park County, Wyoming, United States, in Yellowstone National Park. As of the 2010 census, its population was 263.

The Mammoth Hot Springs Historic District is a 158-acre (64 ha) historic district in Yellowstone National Park comprising the administrative center for the park. It is composed of two major parts: Fort Yellowstone, the military administrative center between 1886 and 1918, and now a National Historic Landmark, and a concessions district which provides food, shopping, services, and lodging for park visitors and employees. It was added to the National Register of Historic Places on March 20, 2002, for its significance in architecture, conservation, entertainment/recreation, and military. The district includes 189 contributing buildings.

U.S. Highway 89 (US 89) is a north-south United States Numbered Highway in the state of Montana. It extends approximately 400.5 miles (644.5 km) from Yellowstone National Park north to the Canadian border. US 89 is an important tourist route within Montana as it connects Yellowstone National Park and Glacier National Park. The section of US 89 located between US 12 and US 87 is known as the Kings Hill Scenic Byway, which passes through the Little Belt Mountains in the Lewis and Clark National Forest, and is home to a wide variety of wildlife and provides many recreational opportunities for travelers along the route.

Gardiner station was a railway station in Gardiner, Montana, serving the Northern Pacific Railway. Gardiner was on the southern terminus of a branch line from Livingston and is at the northern border of Yellowstone National Park. Passengers would be shuttled to/from the park via stagecoach. The station was designed by Robert Reamer in the rustic style. Passenger service eventually diminished from Gardiner, and the station was torn down in 1954.

U.S. Highway 191 (US 191) is a north-south United States Numbered Highway in the state of Montana. It extends approximately 442.2 miles (711.7 km) from Yellowstone National Park north to the Canadian border.

U.S. Route 191 (US 191) is a part of the U.S. Highway System that travels Douglas, Arizona on the Mexican border, north to Loring, Montana on the Canadian border; broken into two segments by Yellowstone National Park where unnumbered park roads serve as a connector. In the state of Wyoming, it extends approximately 289 miles (465 km) from the Utah state line near Dutch John, Utah to the southern entrance of Yellowstone National Park. The current US 191 alignment through Wyoming was established in 1981, replacing U.S. Route 187 (US 187) and Wyoming Highway 373 (WYO 373), making it relatively new compared to other U.S. Highways.

Angling in Yellowstone National Park is a major reason many visitors come to the park each year and since it was created in 1872, the park has drawn anglers from around the world to fish its waters. In 2006, over 50,000 park fishing permits were issued to visitors. The park contains hundreds of miles of accessible, high-quality trout rivers containing wild trout populations—over 200 creeks, streams and rivers are fishable. There are 45 fishable lakes and several large lakes are easily accessible to visitors. Additionally, the park's remote sections provide anglers ample opportunity to visit rivers, streams, creeks and lakes that receive little angling pressure. With the exception of one specially designated drainage, all the park's waters are restricted to artificial lures and fly fishing. The Madison, Firehole and a section of the Gibbon rivers are restricted to fly fishing only.

Soda Butte Creek is an approximately 20 miles (32 km) long major tributary of the Lamar River in Yellowstone National Park. It is named for a now-extinct geyser (Soda Butte) near its mouth. Soda Butte and the creek were named by A. Bart Henderson, a Cooke City miner, in 1870. It rises just outside the northeast corner of the park on the southern slopes of the Absaroka Range near Cooke City, Montana. The Northeast East Entrance road parallels Soda Butte Creek for its entire length within the park. Soda Butte Creek is a popular angling destination for native Yellowstone cutthroat trout.

Specimen Ridge, el. 8,379 feet (2,554 m) is an approximately 8.5-mile (13.7 km) ridge along the south rim of the Lamar Valley in Yellowstone National Park. The ridge separates the Lamar Valley from Mirror Plateau. The ridge is oriented northwest to southeast from the Tower Junction area to Amethyst Mountain. The ridge is known for its abundance of amethyst, opal and petrified wood. It was referred to as Specimen Mountain by local miners and was probably named by prospectors well before 1870. The south side of the ridge is traversed by the 18.8-mile (30.3 km) Specimen Ridge Trail between Tower Junction and Soda Butte Creek. The trail passes through the Petrified Forest and over the summit of Amethyst Mountain el. 9,614 feet (2,930 m).

Whistler Geyser is a series of small steaming holes in the Joseph's Coat Springs Thermal Area on the western edge of the Mirror Plateau at the head of Broad Creek in Yellowstone National Park. The Joseph's Coat Springs Thermal Area is an isolated thermal feature not accessed by any marked trail. The Whistler Geyser was discovered by Capt W. A. Jones in 1873 during the Hayden Geological Survey of 1873. In 1884, Arnold Hague and Walter Weed visited the area and documented the thermal features during the Hague Geological Survey. Hague named the vent Whistler because of the noise it made.

Trilobite Point is a mountain peak in the southern section of the Gallatin Range in Yellowstone National Park. It has an elevation of 10,010 feet (3,050 m). In 1883, William Henry Holmes of the Hayden expedition named it after trilobite-bearing exposures of Cambrian sedimentary strata that he found just below its summit and around it.

The Grand Canyon of the Yellowstone is the first large canyon on the Yellowstone River downstream from Yellowstone Falls in Yellowstone National Park in Wyoming. The canyon is approximately 24 miles (39 km) long, between 800 and 1,200 ft (240 and 370 m) deep and from 0.25 to 0.75 mi (0.40 to 1.21 km) wide.

Hayden Valley is a large, sub-alpine valley within Yellowstone National Park straddling the Yellowstone River between Yellowstone Falls and Yellowstone Lake. The valley floor along the river is an ancient lake bed from a time when Yellowstone Lake was much larger.

The Fishing Bridge Museum is one of a series of "trailside museums" in Yellowstone National Park, Wyoming, United States, designed by architect Herbert Maier in a style that has become known as National Park Service Rustic. It is one of three parts of a 1987-declared National Historic Landmark, the Norris, Madison, and Fishing Bridge Museums. It was not listed separately on the National Register of Historic Places as the other two were. Built in 1931, the Fishing Bridge Museum is the largest in the series, and is used as a small visitor center. The museum displays stuffed mounts of birds and animals found in Yellowstone Park.

The Lake Fish Hatchery Historic District comprises nine buildings built between 1930 and 1932 by the U.S. Fish and Wildlife Service in the National Park Service Rustic style. The buildings exhibit a consistency of style and construction, with exposed gable trusses and oversized paired logs at the corners, all with brown paint. The district is located on the shore of Yellowstone Lake near the Lake Hotel The hatchery was established to provide Yellowstone cutthroat trout eggs for state and federal hatcheries outside Yellowstone.

Uncle Tom's Trail was a steep stairway descent from the south rim of the Grand Canyon of the Yellowstone to a viewpoint near the base of the Lower Yellowstone Falls in Yellowstone National Park. The trail was constructed in 1898 by park concessionaire, "Uncle Tom" H. F. Richardson when the Department of the Interior granted Richardson a permit to operate a ferry across the Yellowstone River. He ferried park visitors across the Yellowstone River above the current site of the Chittenden Memorial Bridge then escorted them to the trail and they traveled down to the base of the Lower Falls via ladders and ropes. Upon their return, visitors were provided a picnic lunch on the south rim of the canyon before returning via the ferry. In 1903 when the original Chittenden Bridge was built, Richardson's ferry business began to decline. In 1905, when the government built a wooden stairway, visitors were increasingly unwilling to pay Richardson the $1 fee for the tour to the base of the falls. 1906 was the last year he operated tours in the canyon.

The largest wildfire in the recorded history of Yellowstone National Park in the United States took place in 1988. Starting as many smaller individual fires, the flames quickly spread out of control due to drought conditions and increasing winds, combining into several large conflagrations which burned for several months. The fires almost destroyed two major visitor destinations and, on September 8, 1988, the entire park was closed to all non-emergency personnel for the first time in its history. Only the arrival of cool and moist weather in the late autumn brought the fires to an end. A total of 793,880 acres (321,272 ha), or 36 percent of the national park, burned at varying levels of severity.

Marshall's Hotel, subsequently known as the Firehole Hotel was the first public accommodations built in the Firehole River geyser basins of Yellowstone National Park and among the earliest tourist hotels in Yellowstone. The first hotel was built in 1880 by George W. Marshall (1838-1917) and his partner John B. Goff and was located just west of confluence of the Firehole River and Nez Perce Creek. A second hotel, the Firehole Hotel, was built in 1884 in partnership with George Graham Henderson very near the present day Nez Perce Picnic area. The hotels operated for eleven years under various ownership ceasing operation in 1891. By 1895, all the structures except a few cabins associated with the two hotels had been razed.

Mount Jackson el. 8,231 feet (2,509 m) is a mountain peak just north of the Madison River, in the Gallatin Range of Yellowstone National Park. Mount Jackson is named in honor of William Henry Jackson, chief photographer of the Hayden Geological Survey of 1871 and a member of several subsequent geological surveys in the park. Jackson's photographs are some of the earliest ever taken in Yellowstone. The name was suggested by a park naturalist in 1935 but not awarded until 1937 when Jackson, who was still living gave his approval. Jackson visited the park regularly until his death in 1942.

Black Pool is a hot spring in the West Thumb Geyser Basin of Yellowstone National Park in the United States.

The Mountain states (also known as the Mountain West or the Interior West) form one of the nine geographic divisions of the United States that are officially recognized by the United States Census Bureau. It is a subregion of the Western United States.

The Yellowstone hotspot is a volcanic hotspot in the United States responsible for large scale volcanism in Idaho, Montana, Nevada, Oregon, and Wyoming, formed as the North American tectonic plate moved over it. It formed the eastern Snake River Plain through a succession of caldera-forming eruptions. The resulting calderas include the Island Park Caldera, Henry's Fork Caldera, and the Bruneau-Jarbidge caldera. The hotspot currently lies under the Yellowstone Caldera. The hotspot's most recent caldera-forming supereruption, known as the Lava Creek Eruption, took place 640,000 years ago and created the Lava Creek Tuff, and the most recent Yellowstone Caldera. The Yellowstone hotspot is one of a few volcanic hotspots underlying the North American tectonic plate; another example is the Anahim hotspot.

The Yellowstone Plateau Volcanic Field, also known as the Yellowstone Supervolcano or the Yellowstone Volcano, is a complex volcano, volcanic plateau and volcanic field located mostly in the western U.S. state of Wyoming, but it also stretches into Idaho and Montana. It is a popular site for tourists.

The Yellowstone Caldera, also known as the Yellowstone Plateau Volcanic Field, is a Quaternary volcanic field, caldera complex, and volcanic plateau spanning parts of Wyoming, Idaho, and Montana. It is driven by the Yellowstone hotspot and lies largely within Yellowstone National Park. The field comprises several overlapping caldera structures, multiple lava domes and resurgent domes, and numerous bimodal lavas and tuffs of basaltic and rhyolitic composition, originally covering about 17,000 km² (6,600 mi²).

Big Cub Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States.

Fan and Mortar Geysers are two geysers in the Upper Geyser Basin in Yellowstone National Park. For the past several decades, they have erupted in concert with one another and are generally talked about together. The records detailing these geysers' known eruptive history shows that they have been infrequent and irregular performers.

Craig Pass (el.8,262 feet (2,518 m)), is a mountain pass located on the Continental Divide in Yellowstone National Park in Wyoming, United States. The Grand Loop Road crosses the pass approximately 8 miles (13 km) east of Old Faithful Geyser.

Vent Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States.

The Lava Creek Tuff is a voluminous sheet of ash-flow tuff located in Wyoming, Montana and Idaho, United States. It was created during the Lava Creek eruption around 640,000 years ago, which led to the formation of the Yellowstone Caldera. This eruption is considered the climactic event of Yellowstone's third volcanic cycle. The Lava Creek Tuff covers an area of more than 7,500 km² (2,900 mi²) centered around the caldera and has an estimated magma volume of 1,000 km³ (240 cu mi).

Wealaka was a community established in 1880 in the Creek Nation, Indian Territory. It is notable as the site of Wealaka Mission, which operated a school from 1882-1907. This school was primarily for Muscogee Creek children, but European Americans could attend for a fee. After statehood in 1907, the site was sold to private owners.

The Yellowstone Volcano Observatory (YVO) is a volcano observatory that primarily monitors the Yellowstone Caldera in Yellowstone National Park in the United States. The observatory's jurisdiction also includes volcanic centers in the states of Colorado, Utah, Arizona, and New Mexico. As with other U.S. volcano observatories, it is funded through the United States Geological Survey Volcano Hazards Program.

The Lewis River is an 18.1-mile-long (29.1 km) tributary of the Snake River. The entire course of the river is located within the boundaries of Yellowstone National Park in Wyoming, US. The river is named for Meriwether Lewis, commander of the Lewis and Clark Expedition.

Brilliant Pool is a hot spring in the Upper Geyser Basin of Yellowstone National Park in the United States. Brilliant Pool is part of the Daisy Group and is interconnected with the Daisy and Splendid Geysers. Prior to an eruption by Daisy or Splendid, the pool is filled.

The Old Faithful Historic District in Yellowstone National Park comprises the built-up portion of the Upper Geyser Basin surrounding the Old Faithful Inn and Old Faithful Geyser. It includes the Old Faithful Inn, designed by Robert Reamer and is itself a National Historic Landmark, the upper and lower Hamilton's Stores, the Old Faithful Lodge, designed by Gilbert Stanley Underwood, the Old Faithful Snow Lodge, and a variety of supporting buildings. The Old Faithful Historic District itself lies on the 140-mile Grand Loop Road Historic District.

The Old Faithful Museum of Thermal Activity was one of a series of four "trailside" museums built in Yellowstone National Park in 1929. Funded by a grant of $118,000 from Laura Spelman Rockefeller, the museums interpreted park features for visitors, and represented an early version of the visitor information center concept that became widespread throughout the National Park Service. The four museums were notable examples of the National Park Service Rustic style, and all were designed by Park Service architect Herbert Maier. The surviving Norris Museum, Fishing Bridge Museum and the Madison Museum are collectively listed as National Historic Landmarks.

West Triplet Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park, Wyoming. West Triplet Geyser is 85 feet (26 m) south of Grand Geyser. Its activity is related to that of Grand and Rift geysers. West Triplet erupts to a height of about 10 feet (3.0 m), usually during Grand's quiet periods. Before 1947 it displayed regular activity, erupting about every three hours.

Black Sand Basin is one of a grouping of geothermal hot springs and geysers located in the Upper Geyser Basin of Yellowstone National Park, Wyoming. The spring is too hot to use as a mineral bath as its scalding 200 °F (93 °C) or hotter water has proven to be fatal. In the winter, a marked ski trail runs from the Old Faithful Visitor Center to Black Sand Basin

Blue Star Spring is a hot spring in the Upper Geyser Basin of Yellowstone National Park in the United States. It is named for its distinctive star shape. The spring has very rarely exhibited geyser activity with the last eruption in 2002. The remains of a bison calf lay at the bottom of the pool after it fell down. The average temperature of the pool is 190.7 °F (88.2 °C).

Ear Spring is a hot spring in the Upper Geyser Basin of Yellowstone National Park in the United States. Located close to Old Faithful, on rare occasions Ear Spring will erupt as a geyser, and can shoot rocks and debris as well as water more than 25 feet (7.6 m) for a few minutes. On September 15, 2018, Ear Spring was seen on the National Park Service webcam at Old Faithful erupting for a minute and reached heights of 20 to 30 ft (6.1 to 9.1 m). This was the largest eruption the pool may have had since 1957. The eruption tossed small rocks out along with trash that people had thrown in it over the years and the heated water killed the surrounding bacterial mats that normally thrive in less heated conditions. Likely related to the eruption of Ear Spring, a new thermal feature opened up under the pedestrian boardwalk near Pump Geyser which resulted in the National Park Service temporarily closing off the boardwalk. This new thermal feature was spouting water the night of September 18–19, 2018. Additionally, Doublet Pool and North Goggles Geyser have both been more active in the period immediately after the rare eruption of Ear Spring.

Emerald Pool, a hot spring named for its emerald green color, is one of the main attractions at Black Sand Basin Hot Springs in Yellowstone National Park. Its temperature is 154.6 °F (68.1 °C) and its dimensions are 27 by 38 feet (8.2 by 11.6 m) with a depth of 25 feet (7.6 m). The color is due to growth of yellow bacteria and algae. Cooling, the result of objects thrown into the pool and natural debris, has affected the growth of the bacteria and algae, making the pool appear orange and brown around the edges.

Lost Dakota was a small, uninhabited portion of land that was left over after the division and organization of the large former Dakota Territory into new territories in the late 19th century.

Crawfish Creek is a short stream in Yellowstone National Park in the U.S. state of Wyoming This watercourse is known for its unusually warm temperatures compared to other surface water bodies in Wyoming; these elevated temperatures enable crawfish to thrive in the water. Summer water temperatures are in the range of 22 to 24 degrees Celsius; pH levels are typically about 9.1, or somewhat alkaline. The warm waters come from a southern portion of the Yellowstone volcanic zone which produces hot water from hot springs and fumaroles in the area. The stream feeds into the Lewis River just south of the Lewis River Canyon and just before the Lewis River converges with the Snake River.

Fall River rises on the Madison and Pitchstone Plateaus in the southwest corner of Yellowstone National Park, Wyoming and flows approximately 64 miles (103 km) to its confluence with the Henrys Fork of the Snake River near Ashton, Idaho. Historically, the river was referred to as the Middle Fork of the Snake River or as Fall River or the Falls River by trappers and prospectors as early as the 1830s. It was officially named the Falls River by the 1872 Hayden Geological Survey, but was always called Fall River by the locals and so the U.S. Board on Geographic Names changed the official name to Fall River in 1997 at the request of Idaho authorities. The river is home to numerous waterfalls and cascades in its upper reaches.

U.S. Route 89 (US 89) is a part of the U.S. Highway System that travels Flagstaff, Arizona, north to the Canadian border; broken into two segments by Yellowstone National Park where unnumbered park roads serve as a connector. In the state of Wyoming, it extends approximately 156 miles (251 km) from the Idaho state line near Geneva, Idaho to the southern entrance of Yellowstone National Park. US 89 passes through many scenic sites including Grand Teton National Park, the Jackson Hole valley, the Snake River Canyon, and Star Valley and is the backbone visitor highway for two U.S. National Parks.

U.S. Route 287 (US 287) is a part of the U.S. Highway System that travels from Port Arthur, Texas northwest to Choteau, Montana; broken into two segments by Yellowstone National Park where unnumbered park roads serve as a connector. In the state of Wyoming, it extends approximately 463 miles (745 km) from the Colorado state line near Tie Siding to the southern entrance of Yellowstone National Park.

Colonnade Falls ht. upper 35 feet (11 m), ht. lower 67 feet (20 m) is a set of two waterfalls on the Bechler River in Yellowstone National Park. Colonnade Falls is accessible via the Bechler River Trail. The falls were named in 1885 by members of the Arnold Hague Geological Survey probably because the falls resemble a row of columns at regular intervals.

The Bechler River is a remote major river flowing southwest entirely within the confines of Yellowstone National Park to its confluence with the Fall River in the southwest section of the park. The river was named by Frank Bradley, a member of the 1872 Hayden Geological Survey for cartographer and explorer Gustavus R. Bechler, the chief surveyor and mapmaker on the survey. Henry Gannett also a member of the survey claimed that Bechler discovered the river, but trapper Osborne Russell explored the area in 1830.

The Zone of Death is the 50-square-mile (130 km²) area in the Idaho section of Yellowstone National Park in which, as a result of the Vicinage Clause in the Constitution of the United States, and that this park is a federal enclave, a person may be able theoretically to avoid conviction for any major crime, including murder.
