The Black Rock Desert is a semi-arid region of lava beds and playa, or alkali flats, situated in the Black Rock Desert–High Rock Canyon Emigrant Trails National Conservation Area, a silt playa 100 miles (160 km) north of Reno, Nevada that encompasses more than 300,000 acres (120,000 ha) of land and contains more than 120 miles (200 km) of historic trails. It is in the northern Nevada section of the Great Basin with a lakebed that is a dry remnant of Pleistocene Lake Lahontan.
The Feather River is the principal tributary of the Sacramento River, in the Sacramento Valley of Northern California. The river's main stem is about 73 miles (117 km) long. Its length to its most distant headwater tributary is just over 210 miles (340 km). The main stem Feather River begins in Lake Oroville, where its four long tributary forks join—the South Fork, Middle Fork, North Fork, and West Branch Feather Rivers. These and other tributaries drain part of the northern Sierra Nevada, and the extreme southern Cascades, as well as a small portion of the Sacramento Valley. The total drainage basin is about 6,200 square miles (16,000 km2), with approximately 3,604 square miles (9,330 km2) above Lake Oroville.
The Virgin Mountains are a mountain range of the northeastern Mojave Desert, located in Clark County, southeastern Nevada and Mohave County, northwestern Arizona.
Black Butte is an extinct stratovolcano in the U.S. state of Oregon. Located in Jefferson County, it is part of Deschutes National Forest. Black Butte forms part of the Cascade volcanic arc. The butte lies just south of the Metolius Springs, which merge to form the headwaters of the Metolius River. The Metolius River's basin sustains a wide array of plant life, large and small mammals, and more than 80 bird species.
Aspen Butte is a steep-sided shield volcano in the Cascade Range of southern Oregon. It is located 15 miles (24 km) south of Pelican Butte and 15 miles (24 km) southeast of Mount McLoughlin. It rises over 4,000 feet (1,200 m) above the nearby shore of Upper Klamath Lake. Ice Age glaciers carved three large cirques into the north and northeast flanks of the mountain removing most of the original summit area including any evidence of a crater. The summit is now the high point along the curving ridge which bounds the southern edge of the cirques above steep cliffs.
The Jackson Mountains are a north-northeast trending mountain range in southwestern Humboldt County, Nevada. The range is flanked on the west by the Black Rock Desert and the Black Rock Range beyond. To the north across the Quinn River and Nevada State Route 140 lie the Bilk Creek Mountains. To the northeast across Kings River Valley is the Double Mountains and to the east are the Sleeping Hills. To the southeast and south lie the Eugene and Kamma Mountains. The ghost town of Sulphur lies just southwest of the pass between the Jackson and Kamma ranges. Nevada State Route 49 and the Union Pacific railroad Feather River Route traverse this pass.
Blacktail Butte is a butte mountain landform rising from Jackson Hole valley in Grand Teton National Park in the U.S. state of Wyoming. Blacktail Butte was originally named Upper Gros Ventre Butte in an early historical survey conducted by the U.S. Geological Survey. Most of Blacktail Butte is densely forested with a mixed fir forest of lodgepole pine, Douglas fir and Engelmann spruce, with scattered pockets of aspen. There are several large sedimentary rock outcroppings, which are used by rock climbers. This butte is a principal landmark in Jackson Hole, with much of the Jackson Hole valley floor and many portions of the Teton Range visible from its hillsides.
Crested Butte is a prominent mountain summit in the Elk Mountains range of the Rocky Mountains of North America. The 12,168-foot (3,709 m) peak is in Gunnison National Forest, 2.1 miles (3.4 km) northeast by east of the Town of Crested Butte in Gunnison County, Colorado, United States. Ski lifts and runs of the Crested Butte Mountain Resort occupy the north side of the mountain.
The Black Mountains, a mid-Miocene formation, in Nevada are a series of rugged, arid rocky volcanic mountains ranging in elevations to 3310 ft. The range lies on the north shore of Lake Mead, at the southwest corner of the Overton Arm, about 25 mi south of Overton, Nevada.
The Eldorado Mountains, also called the El Dorado Mountains, are a north-south trending mountain range in southeast Nevada bordering west of the south-flowing Colorado River; the endorheic Eldorado Valley borders the range to the west, and the range is also on the western border of the Colorado River's Black Canyon of the Colorado, and El Dorado Canyon on the river. The range is 50 miles (80 km) southeast of Las Vegas, Nevada; and the Eldorado Mountains connect with the Highland and Newberry mountains.
The Muddy Mountains are a large mountain range in Clark County, Nevada.
Temescal Mountains, also known as the Sierra Temescal, are one of the northernmost mountain ranges of the Peninsular Ranges in western Riverside County, in Southern California in the United States. They extend for approximately 25 mi (40 km) southeast of the Santa Ana River east of the Elsinore Fault Zone to the Temecula Basin and form the western edge of the Perris Block.
The Perris Block is the central block of three major fault-bounded blocks of the northern part of the Peninsular Ranges. The Perris Block lies between the Santa Ana Block to the west and the San Jacinto Block to the east. The Perris Block, was named by Walter A. English in 1925 for the city of Perris, located near the center of the block.
Boulder Canyon, originally Devils Gate Canyon, is a canyon on the Colorado River, above Hoover Dam, now flooded by Lake Mead. It lies between Clark County, Nevada and Mohave County, Arizona. It heads at western end of the Virgin River Basin of Lake Mead, at about 36°09′05″N114°32′51″W. Boulder Canyon divides the Black Mountains into the Black Mountains of Arizona, and the Black Mountains of Nevada. Its mouth is now under the eastern end of the Boulder Basin of Lake Mead, between Canyon Point in Nevada and Canyon Ridge in Arizona. Its original mouth is now underneath Lake Mead between Beacon Rock and Fortification Ridge on the southern shore in Arizona.
Icicle Ridge is a mountain ridge located in the eastern border of the Alpine Lakes Wilderness, in the Washington state, United States. Several trails lead to Icicle Ridge which borders several prominent mountains, peaks, and lakes. Icicle Ridge is located at the western edge of the city of Leavenworth on land managed by the Okanogan–Wenatchee National Forest.
