Great Basin National Park is a national park of the United States located in White Pine County in east-central Nevada, near the Utah border, established in 1986. The park is most commonly entered by way of Nevada State Route 488, which is connected to U.S. Routes 6 and 50 by Nevada State Route 487 via the small town of Baker, the closest settlement.
Rocky Mountain National Park is a national park of the United States located approximately 55 mi (89 km) northwest of Denver in north-central Colorado, within the Front Range of the Rocky Mountains. The park is situated between the towns of Estes Park to the east and Grand Lake to the west. The eastern and western slopes of the Continental Divide run directly through the center of the park with the headwaters of the Colorado River located in the park's northwestern region. The main features of the park include mountains, alpine lakes and a wide variety of wildlife within various climates and environments, from wooded forests to mountain tundra.
Sequoia National Park is a national park of the United States in the southern Sierra Nevada east of Visalia, California. The park was established on September 25, 1890, and today protects 404,064 acres of forested mountainous terrain. Encompassing a vertical relief of nearly 13,000 feet (4,000 m), the park contains the highest point in the contiguous United States, Mount Whitney, at 14,505 feet (4,421 m) above sea level. The park is south of, and contiguous with, Kings Canyon National Park; both parks are administered by the National Park Service together as Sequoia and Kings Canyon National Parks. UNESCO designated the areas as Sequoia-Kings Canyon Biosphere Reserve in 1976.
The Wasatch Range or Wasatch Mountains is a mountain range in the western United States that runs about 160 miles (260 km) from the Utah-Idaho border south to central Utah. It is the western edge of the greater Rocky Mountains, and the eastern edge of the Great Basin region. The northern extension of the Wasatch Range, the Bear River Mountains, extends just into Idaho, constituting all of the Wasatch Range in that state.
The Bighorn Mountains are a mountain range in northern Wyoming and southern Montana in the United States, forming a northwest-trending spur from the Rocky Mountains extending approximately 200 mi (320 km) northward on the Great Plains. They are separated from the Absaroka Range, which lie on the main branch of the Rockies to the west, by the Bighorn Basin. Much of the land is contained within the Bighorn National Forest.
The geology of the Grand Canyon area includes one of the most complete and studied sequences of rock on Earth. The nearly 40 major sedimentary rock layers exposed in the Grand Canyon and in the Grand Canyon National Park area range in age from about 200 million to nearly 2 billion years old. Most were deposited in warm, shallow seas and near ancient, long-gone sea shores in western North America. Both marine and terrestrial sediments are represented, including lithified sand dunes from an extinct desert. There are at least 14 known unconformities in the geologic record found in the Grand Canyon.
Mount Timpanogos, often referred to as Timp, is the second-highest mountain in Utah's Wasatch Range. Timpanogos rises to an elevation of 11,752 ft (3,582 m) above sea level in the Uinta-Wasatch-Cache National Forest. With 5,270 ft (1,610 m) of topographic prominence, Timpanogos is the 47th-most prominent mountain in the contiguous United States.
The Ruby Mountains are a mountain range, primarily located within Elko County with a small extension into White Pine County, in Nevada, United States. Most of the range is included within the Humboldt-Toiyabe National Forest. The range reaches a maximum elevation of 11,387 feet (3,471 m) on the summit of Ruby Dome. To the north is Secret Pass and the East Humboldt Range, and from there the Rubies run south-southwest for about 80 miles (130 km). To the east lies Ruby Valley, and to the west lie Huntington and Lamoille Valleys. The Ruby Mountains are the only range of an introduced bird, the Himalayan snowcock, in North America. The mountain range was named after the garnets found by early explorers. The central core of the range shows extensive evidence of glaciation during recent ice ages, including U-shaped canyons, moraines, hanging valleys, and steeply carved granite mountains, cliffs, and cirques.
Oak Creek Canyon is a river gorge located in northern Arizona between the cities of Flagstaff and Sedona. The canyon is often described as a smaller cousin of the Grand Canyon because of its scenic beauty. State Route 89A enters the canyon on its north end via a series of hairpin turns before traversing the bottom of the canyon for about 13 miles (21 km) until the highway enters the town of Sedona.
Quercus chrysolepis, commonly termed canyon live oak, canyon oak, golden cup oak or maul oak, is a North American species of evergreen oak that is found in Mexico and in the western United States, notably in the California Coast Ranges. This tree is often found near creeks and drainage swales growing in moist cool microhabitats. Its leaves are a glossy dark green on the upper surface with prominent spines; a further identification arises from the leaves of canyon live oak being geometrically flat.
North Fork Mountain is a quartzite-capped mountain ridge in the Ridge and Valley physiographic province of the Allegheny Mountains, also known as the High Alleghenies or Potomac Highlands, of eastern West Virginia. Kile Knob, at 4,588 feet, is the mountain's highest point, and Panther Knob and Pike Knob are nearly as high.
The Cheat Mountain salamander is a species of small woodland salamander in the family Plethodontidae. The species is found only on Cheat Mountain, and a few nearby mountains, in the eastern highlands of West Virginia. It and the West Virginia spring salamander are the only vertebrate species with geographic ranges restricted to that state.
The Madison Limestone is a thick sequence of mostly carbonate rocks of Mississippian age in the Rocky Mountain and Great Plains areas of the western United States. The rocks serve as an important aquifer as well as an oil reservoir in places. The Madison and its equivalent strata extend from the Black Hills of western South Dakota to western Montana and eastern Idaho, and from the Canada–United States border to western Colorado and the Grand Canyon of Arizona.
Smoke Hole Canyon — traditionally called The Smoke Holes and later simply Smoke Hole — is a rugged 20 miles (32 km) long gorge carved by the South Branch Potomac River in the Allegheny Mountains of eastern West Virginia, United States. The area is rather isolated and remote with parts accessible only by boat or on foot.
The Blue Mountains ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the Pacific Northwest, mainly in the state of Oregon, with small areas over the state border in Idaho and southeastern Washington. It is also contiguous with the World Wildlife Fund's Blue Mountain forests ecoregion.
The Klamath Mountains ecoregion of Oregon and California lies inland and north of the Coast Range ecoregion, extending from the Umpqua River in the north to the Sacramento Valley in the south. It encompasses the highly dissected ridges, foothills, and valleys of the Klamath and Siskiyou Mountains. It corresponds to the Level III ecoregion designated by the Environmental Protection Agency and to the Klamath-Siskiyou forests ecoregion designated by the World Wide Fund for Nature.
Spearfish Canyon is a deep but narrow gorge carved by Spearfish Creek located in Lawrence County, South Dakota, U.S., just south of Spearfish. The canyon is located within the Black Hills, located on the northern edge of the Black Hills National Forest. The Spearfish Canyon Scenic Byway travels through the Canyon from Spearfish to Cheyenne Crossing along U.S. Route 14A. The highway follows an old railroad grade that was abandoned after massive flooding in 1933.
The Arizona Mountains forests are a temperate coniferous forests ecoregion of the southwest United States with a rich variety of woodland habitats and wildlife.
The ecology of the Rocky Mountains is diverse due to the effects of a variety of environmental factors. The Rocky Mountains are the major mountain range in western North America, running from the far north of British Columbia in Canada to New Mexico in the southwestern United States, climbing from the Great Plains at or below 1,800 feet (550 m) to peaks of over 14,000 feet (4,300 m). Temperature and rainfall varies greatly also and thus the Rockies are home to a mixture of habitats including the alpine, subalpine and boreal habitats of the Northern Rocky Mountains in British Columbia and Alberta, the coniferous forests of Montana and Idaho, the wetlands and prairie where the Rockies meet the plains, a different mix of conifers on the Yellowstone Plateau in Wyoming, the montane forests of Utah, and in the high Rockies of Colorado and New Mexico, and finally the alpine tundra of the highest elevations.
Cuarenta Casas(literally "40 houses") is an archaeological site in the northern Mexican state of Chihuahua. Construction of the site is attributed to the Mogollon culture.
