The Killdeer Mountains are a mountain range in Dunn County, North Dakota, United States. [1] It consists of two mesas, North Mountain and South Mountain. Much of the range formation was caused by wind, river and lake erosion.
The Killdeer Mountains cover a surface of 26 square kilometers (10 sq mi). The highest peak reaches 3,281 ft (1,000 m), which is the highest point in the county. [2] [3]
The range's name comes from the Native Americans, who used the area as a hunting ground for deer. [4] The range was the scene of the Battle of Killdeer Mountain in 1864.
In 1906, reports of volcanic activity were coming from the mountains. [5] However, no geological evidence has proven a confirmed volcano in the area.
Mount Baker, also known as Koma Kulshan or simply Kulshan, is a 10,781 ft (3,286 m) active glacier-covered andesitic stratovolcano in the Cascade Volcanic Arc and the North Cascades of Washington State in the United States. Mount Baker has the second-most thermally active crater in the Cascade Range after Mount St. Helens. About 30 miles (48 km) due east of the city of Bellingham, Whatcom County, Mount Baker is the youngest volcano in the Mount Baker volcanic field. While volcanism has persisted here for some 1.5 million years, the current volcanic cone is likely no more than 140,000 years old, and possibly no older than 80–90,000 years. Older volcanic edifices have mostly eroded away due to glaciation.
California is a U.S. state on the western coast of North America. Covering an area of 163,696 sq mi (423,970 km2), California is among the most geographically diverse states. The Sierra Nevada, the fertile farmlands of the Central Valley, and the arid Mojave Desert of the south are some of the geographic features of this U.S. state. It is home to some of the world's most exceptional trees: the tallest, most massive, and oldest. It is also home to both the highest and lowest points in the 48 contiguous states.
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as many of those in the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The highest peak in the range is Mount Rainier in Washington at 14,411 feet (4,392 m).

Mount Hood, also known as Wy'east, is an active stratovolcano in the Cascade Range and is a member of the Cascade Volcanic Arc. It was formed by a subduction zone on the Pacific Coast and rests in the Pacific Northwest region of the United States. It is located about 50 mi (80 km) east-southeast of Portland, on the border between Clackamas and Hood River counties, and forms part of the Mount Hood National Forest. Much of the mountain outside the ski areas is part of the Mount Hood Wilderness. With a summit elevation of 11,249 ft, it is the highest mountain in the U.S. state of Oregon and is the fourth highest in the Cascade Range. Ski areas on the mountain include Timberline Lodge ski area which offers the only year-round lift-served skiing in North America, Mount Hood Meadows, Mount Hood Skibowl, Summit Ski Area, and Cooper Spur ski area. Mt. Hood attracts an estimated 10,000 climbers a year.
Three Fingered Jack is a summit of a shield volcano of the Cascade Range in the U.S. state of Oregon. Formed during the Pleistocene epoch, the mountain consists mainly of basaltic andesite lava and was heavily glaciated in the past. While other Oregon volcanoes that were heavily glaciated—such as Mount Washington and Mount Thielsen—display eroded volcanic necks, Three Fingered Jack's present summit is a comparatively narrow ridge of loose tephra supported by a dike only 10 feet (3.0 m) thick on a generally north–south axis. Glaciation exposed radiating dikes and plugs that support this summit. The volcano has long been inactive and is highly eroded.
White Butte is the highest natural point in the U.S. state of North Dakota. At an elevation of 3,506 ft, it is a prominent butte in Slope County, in the Badlands of the southwestern part of the state. It is located 3 miles east of U.S. 85 and about 6.5 mi (10 km) south of Amidon.
The San Francisco volcanic field is an area of volcanoes in northern Arizona, north of Flagstaff, US. The field covers 1,800 square miles (4,700 km2) of the southern boundary of the Colorado Plateau. The field contains 600 volcanoes ranging in age from nearly 6 million years old to less than 1,000 years, of which Sunset Crater is the youngest. The highest peak in the field is Humphreys Peak, at Flagstaff's northern perimeter: the peak is Arizona's highest at 12,633 feet and is a part of the San Francisco Peaks, an active stratovolcano complex.
The Sutter Buttes are a small circular complex of eroded volcanic lava domes which rise as buttes above the flat plains of the Sacramento Valley in Sutter County, northern California. They are situated just outside Yuba City in the northern part of the state's Central Valley.
Mount Sneffels is the highest summit of the Sneffels Range in the Rocky Mountains of North America. The 14,153-foot (4313.93 m) fourteener is located in the Mount Sneffels Wilderness of Uncompahgre National Forest, 6.7 miles (10.8 km) west by south of the City of Ouray in Ouray County, Colorado, United States. The summit of Mount Sneffels is the highest point in Ouray County.
The Three Sisters are closely spaced volcanic peaks in the U.S. state of Oregon. They are part of the Cascade Volcanic Arc, a segment of the Cascade Range in western North America extending from southern British Columbia through Washington and Oregon to Northern California. Each over 10,000 feet in elevation, they are the third-, fourth- and fifth-highest peaks in Oregon. Located in the Three Sisters Wilderness at the boundary of Lane and Deschutes counties and the Willamette and Deschutes national forests, they are about 10 miles south of the nearest town, Sisters. Diverse species of flora and fauna inhabit the area, which is subject to frequent snowfall, occasional rain, and extreme temperature variation between seasons. The mountains, particularly South Sister, are popular destinations for climbing and scrambling.
The West Elk Mountains are a high mountain range in the west-central part of the U.S. state of Colorado. They lie primarily within the Gunnison National Forest, and part of the range is protected as the West Elk Wilderness. The range is primarily located in Gunnison County, with small parts in eastern Delta and Montrose counties.
Yamsay Mountain is a large shield volcano in the Cascade Range of south-central Oregon, located about 35 miles (56 km) east of Crater Lake on the border between Klamath County and Lake County. It is part of the Cascade Volcanic Arc but is located in a mountain range 30 to 50 miles behind the main Cascade volcanic front. The best known members of this enigmatic arc are the massive shields of Newberry Volcano, about 55 miles (89 km) farther north in Oregon, and Medicine Lake Volcano, about 80 miles (130 km) south in Northern California. Yamsay is the second highest volcano in the eastern arc, almost 300 feet (90 m) higher than Newberry and Medicine Lake.
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 La Garita Mountains are a high mountain range in the San Juan Mountains, a sub-range of the Southern Rocky Mountains. The mountains are located in Saguache and Mineral counties in southwestern Colorado and are almost entirely managed as public land within the Rio Grande National Forest.
The Cochetopa Hills are a mountain range on the Continental Divide in Saguache County, Colorado, United States. The Cochetopa Hills are a sub-range of the San Juan Mountains and are located in the Gunnison National Forest and Rio Grande National Forest. The range extends from Marshall Pass southwest 50 miles (80 km) along the winding crest of the divide to Saguache Park. The high point of the Cochetopa Hills is Long Branch Baldy at an elevation of 11,974 feet (3,650 m).
North Dakota Highway 22 (ND 22) is a 156.051-mile-long (251.140 km) major north–south state highway in North Dakota. It begins at the South Dakota state line south of the small town of Reeder and ends at ND 23 west of New Town and north of Mandaree. The route has one concurrency with U.S. Route 12. The highway widely parallels US 85, running about fifteen miles east of it.
The geology of North Dakota includes thick sequences oil and coal bearing sedimentary rocks formed in shallow seas in the Paleozoic and Mesozoic, as well as terrestrial deposits from the Cenozoic on top of ancient Precambrian crystalline basement rocks. The state has extensive oil and gas, sand and gravel, coal, groundwater and other natural resources.
