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 and has the largest total area covered by a volcano in the Cascade Range.
Mount Thielsen, or Big Cowhorn, is an extinct shield volcano in the Oregon High Cascades, near Mount Bailey. Because eruptive activity ceased 250,000 years ago, glaciers have heavily eroded the volcano's structure, creating precipitous slopes and a horn-like peak. The spire-like shape of Thielsen attracts lightning strikes and creates fulgurite, an unusual mineral. The prominent horn forms a centerpiece for the Mount Thielsen Wilderness, a reserve for recreational activities such as skiing and hiking.
Belknap Crater is a shield volcano in the Cascade Range in the U.S. state of Oregon. Located in Linn County, it is associated with lava fields and numerous subfeatures including the Little Belknap and South Belknap volcanic cones. It lies north of McKenzie Pass and forms part of the Mount Washington Wilderness. Belknap is not forested and most of its lava flows are not vegetated, though there is some wildlife in the area around the volcano, as well as a number of tree molds formed by its eruptive activity.
Gifford Pinchot National Forest is a National Forest located in southern Washington, USA, managed by the United States Forest Service. With an area of 1.32 million acres (5300 km2), it extends 116 km along the western slopes of Cascade Range from Mount Rainier National Park to the Columbia River. The forest straddles the crest of the South Cascades of Washington State, spread out over broad, old growth forests, high mountain meadows, several glaciers, and numerous volcanic peaks. The forest's highest point is at 12,276 ft. at the top of Mount Adams, the second tallest volcano in the state after Rainier. Often found abbreviated GPNF on maps and in texts, it includes the 110,000-acre (450 km2) Mount St. Helens National Volcanic Monument, established by Congress in 1982.
Indian Heaven is a volcanic field in Skamania County in the state of Washington, in the United States. Midway between Mount St. Helens and Mount Adams, the field dates from the Pleistocene to the early Holocene epoch. It trends north to south and is dominated by six small shield volcanoes; these shields are topped by small spatter and cinder cones, and the field includes a number of subglacial volcanoes and tuyas. The northernmost peak in the field is Sawtooth Mountain and the southernmost is Red Mountain; its highest point is Lemei Rock at an elevation of 5,925 feet (1,806 m).
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 extinct stratovolcano complex.
Goat Rocks is an extinct stratovolcano in the Cascade Range, located between Mount Rainier and Mount Adams in southern Washington, in the United States. Part of the Cascade Volcanoes, it was formed by the subduction of the Juan de Fuca Plate under the western edge of the North American Plate. The volcano was active from 3.2 million years ago until eruptions ceased between 1 and 0.5 million years ago. Throughout its complex eruptive history, volcanism shifted from silicic explosive eruptions to voluminous, mafic activity.
Cerro Azul, sometimes referred to as Quizapu, is an active stratovolcano in the Maule Region of central Chile, immediately south of Descabezado Grande. Part of the South Volcanic Zone of the Andes, its summit is 3,788 meters (12,428 ft) above sea level, and is capped by a summit crater that is 500 meters (1,600 ft) wide and opens to the north. Beneath the summit, the volcano features numerous scoria cones and flank vents.
El Jorullo is a cinder cone volcano in Michoacán, central Mexico, on the southwest slope of the central plateau, 33 miles southeast of Uruapan in an area known as the Michoacán-Guanajuato volcanic field. It is about 6 miles (10 km) east-northeast of La Huacana. Its current elevation is 4,360 ft (1,329 m). El Jorullo has four smaller cinder cones which have grown from its flanks. The vents of El Jorullo are aligned in a northeast to southwest direction. Lava from these vents cover nine square km around the volcano. Later eruptions produced lavas that had higher silica contents making them thicker than the earlier basalts and basaltic andesite lavas. El Jorullo's crater is about 1,300 by 1,640 feet wide and 490 feet (150 m) deep.
West Crater is a small lava dome with associated lava flows in southern Washington, United States. Located in Skamania County, it rises to an elevation of 4,131 feet (1,259 m), and forms part of the Cascade Volcanic Arc. It is also part of the Marble Mountain-Trout Creek Hill volcanic field, a little-known Quaternary volcanic field in the southern Cascades of Washington state. The area can be hiked, and can be accessed by roads in the Gifford Pinchot National Forest.
Big Cave is a small shield volcano located in northern California in the Cascade Volcanic Arc of the Pacific Northwest. With an elevation listed at either 4,130 feet (1,260 m) or 4,131 feet (1,259 m), it is the product of subduction of several tectonic plates under the North American Plate, which continues at a rate of 4 centimetres (1.6 in) each year.
The Uinkaret volcanic field is an area of monogenetic volcanoes in northwestern Arizona, United States, located on the north rim of the Grand Canyon.
Putana, sometimes referred to as Jorqencal or Machuca, is a volcano on the border between Bolivia and Chile and close to the Sairecabur volcanic complex. Part of the Central Volcanic Zone of the Andes, its summit is 5,890 metres (19,320 ft) above sea level and contains a summit crater with two smaller craters nested within it. Beneath the summit, the volcano features a number of lava domes and lava flows, some of which originated in flank vents.
The Squaw Ridge lava field, also known as the East Lava Field, is a young basaltic field located in the U.S. state of Oregon southeast of Newberry Volcano. The flow erupted from the Lava Mountain shield and is likely related to the Four Craters Lava Field, both of which were created after Mount Mazama erupted.
Trout Creek Hill is a small Pleistocene basaltic shield volcano in Washington, United States. Located in Skamania County, Trout Creek Hill rises to an elevation of 2,946 feet (898 m). It is part of the Cascade Volcanic Arc, located in the Marble Mountain-Trout Creek Hill volcanic field.
Indian Heaven Wilderness is a protected area located inside the Gifford Pinchot National Forest of southwestern Washington state. The wilderness consists of 20,782 acres (8,410 ha) of broad, forested plateau, with meadows straddling numerous volcanic peaks and at least 150 small lakes, ponds, and marshes. The wilderness also contains the Indian Heaven volcanic field. Originally known to the Indians as "Sahalee Tyee," the area has been and remains culturally important to Native Americans. During the past 9,000 years, the Yakima, Klickitat, Cascades, Wasco, Wishram, and Umatilla tribes gathered in this area for berry picking, fishing, and hunting.
Lemei Rock is a shield volcano, and part of the Indian Heaven polygenetic volcanic field in Washington, United States. It is located midway between Mount St. Helens and Mount Adams, and dates from the Pleistocene and Holocene. Lemei Rock is the highest point at 5,925 feet (1,806 m).
Sawtooth Mountain is a shield volcano, and part of the polygenetic Indian Heaven Volcanic Field in Washington, United States. It is located midway between Mount St. Helens and Mount Adams, and dates from the Pleistocene and Holocene. Sawtooth Mountain is the third highest point at 5,354 feet (1,632 m)in this region. The mountain forms a series of welded volcanic rock spires, an eroded remnant of an ancient shield volcano. Sawtooth Mountain is the third highest point in the Indian Heaven Wilderness Area. While Sawtooth Mountain is not the highest, its craggy appearance makes it one of the most namesake peaks in the Indian Heaven Volcanic Field.
Northern Tibet volcanic field is a volcanic field in China.
