Lava Beds National Monument is located in northeastern California, in Siskiyou and Modoc counties. The monument lies on the northeastern flank of Medicine Lake Volcano, which is the largest volcano by area in the Cascade Range.
Craters of the Moon National Monument and Preserve is a U.S. national monument and national preserve in the Snake River Plain in central Idaho. It is along US 20, between the small towns of Arco and Carey, at an average elevation of 5,900 feet (1,800 m) above sea level.
The Snake River Plain is a geologic feature located primarily within the U.S. state of Idaho. It stretches about 400 miles (640 km) westward from northwest of the state of Wyoming to the Idaho-Oregon border. The plain is a wide, flat bow-shaped depression and covers about a quarter of Idaho. Three major volcanic buttes dot the plain east of Arco, the largest being Big Southern Butte.
The Island Park Caldera, in the U.S. states of Idaho and Wyoming, is one of the world's largest calderas, with approximate dimensions of 80 by 65 km. Its ashfall is the source of the Huckleberry Ridge Tuff that is found from southern California to the Mississippi River near St. Louis. This super-eruption of approximately 2,500 km3 (600 cu mi) occurred 2.1 Ma and produced 2,500 times as much ash as the 1980 eruption of Mount St. Helens. Island Park Caldera has the smaller and younger Henry's Fork Caldera nested inside it.
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.
Fort Rock is a tuff ring located on an ice age lake bed in north Lake County, Oregon, United States. The ring is about 4,460 feet (1,360 m) in diameter and stands about 200 feet (60 m) high above the surrounding plain. Its name is derived from the tall, straight sides that resemble the palisades of a fort. The region of Fort Rock–Christmas Lake Valley basin contains about 40 such tuff rings and maars and is located in the Brothers Fault Zone of central Oregon's Great Basin. William Sullivan, an early settler in the area, named Fort Rock in 1873 while searching for lost cattle.
Hell's Half Acre Lava Field is a basaltic lava plain located on the Snake River Plain of Idaho in the United States. It is the easternmost of the basaltic lava fields on the Snake River Plain, located about 25 miles (40 km) west of Idaho Falls, Idaho and 30 miles (48 km) north of Pocatello, Idaho. In 1976, the National Park Service designated the northwestern portion of the site a National Natural Landmark. In 1986, the Bureau of Land Management recommended that 68,760 acres (27,830 ha) of the site, located just southeast of the National Natural Landmark, to be a wilderness study area.
Big Southern Butte is the largest and youngest of three rhyolitic domes formed over a million years near the center of the Eastern Snake River Plain in the U.S. state of Idaho. It is one of the largest volcanic domes on earth. It rises approximately 2500 vertical feet above the lava plain in southern Butte County, east of Craters of the Moon National Monument.
Wilson Butte Cave is located on the Snake River plain in Jerome County northeast of Twin Falls and southeast of Shoshone, Idaho. Listed on the National Register of Historic Places as an archeological site, it is maintained by the Bureau of Land Management (BLM).
A volcanic dam is a type of natural dam produced directly or indirectly by volcanism, which holds or temporarily restricts the flow of surface water in existing streams, like a man-made dam. There are two main types of volcanic dams, those created by the flow of molten lava, and those created by the primary or secondary deposition of pyroclastic material and debris. This classification generally excludes other, often larger and longer lived dam-type geologic features, separately termed crater lakes, although these volcanic centers may be associated with the source of material for volcanic dams, and the lowest portion of its confining rim may be considered as such a dam, especially if the lake level within the crater is relatively high.
Fort Rock–Christmas Lake Valley is a basin of a former inland sea that existed in that region from Pliocene through late Pleistocene time.
The North and South Menan Buttes in southeastern Idaho are two of the world's largest volcanic tuff cones. The two cones, with four smaller associated cones, align along a north-northwest line and comprise the Menan Complex. The buttes rise about 800 feet above the surrounding Snake River plain and are late Pleistocene in age, dating to approximately 10,000 YBP. The South Menan Butte is currently in private hands, however North Menan Butte is publicly owned and has been designated as a National Natural Landmark and a Research Natural Area by the United States Congress. The US Bureau of Land Management designated the North Butte as an Area of Critical Environmental Concern (ACEC).
The David A. Johnston Cascades Volcano Observatory (CVO) is a volcano observatory in the US that monitors volcanoes in the northern Cascade Range. It was established in the summer of 1980, after the eruption of Mount St. Helens. The observatory is named for United States Geological Survey (USGS) volcanologist David A. Johnston, who was swept away in the Mount St. Helens eruption on the morning of May 18, 1980. The observatory's current territory covers Oregon, Washington, and Idaho. The Cascade Range's extent includes northern California, and Cascade volcanoes in that state, such as Mount Shasta and Lassen Peak, previously fell under the CVO's jurisdiction. However, these volcanoes now fall under the jurisdiction of the California Volcano Observatory (CalVO), formed in February 2012 and based in Menlo Park, California, which monitors and researches volcanic activity throughout California and Nevada.
The Black Butte Crater Lava Field, formerly known as Shoshone Lava Field is a lava plain in the U.S. state of Idaho, located in Lincoln County north of the city of Shoshone.
The Guffey Butte–Black Butte Archeological District is a 14,000 acres (57 km2) historic district in southwestern Idaho, United States, that is listed on the National Register of Historic Places (NRHP). It includes numerous archeological sites in Ada, Canyon, Elmore, and Owyhee counties.
The Shale Butte Wilderness Study Area is a Bureau of Land Management wilderness study area (WSA) in Lincoln County, Idaho. It covers 15,560 acres (6,300 ha). The WSA is located to the south of Craters of the Moon National Monument and Preserve.
The six national parks, reserves, historic sites, and monuments in Idaho contain a wide variety of interesting places and experiences. These include recreational areas, archeological sites, nature preserves and volcanic parks.
The Sand Butte Wilderness Study Area is a Bureau of Land Management wilderness study area (WSA) in Lincoln County, Idaho. It covers about 21,000 acres (8,500 ha). The WSA is located to the south of Craters of the Moon National Monument and Preserve.
East Butte is a 6,572-foot elevation (2,003 m) summit located in Bingham County, Idaho, United States.
Middle Butte is a 6,391-foot elevation (1,948 m) summit located in Bingham County, Idaho, United States.
