The Hell's Half Acre lava plain is located in Bingham and Bonneville counties in the state of Idaho. The site is about 150 square miles (390 km 2) in size. [1] The area where a former lava lake existed is marked by a 875-yard (800 m) long by 328-yard (300 m) wide depression near the summit of the lava field. [7]
The two main types of lava field structures are defined as sheet flow lava and pillow lava. Sheet flow lava appears like a wrinkled or folded sheet, while pillow lava is bulbous, and often looks like a pile of pillows atop one another. [2] An important aspect of lava flow morphology is a phenomenon known as lava flow inflation.
The largest of the Northern Basin and Range subregions, the High Lava Plains covers 10,262 square miles (26,578 km 2) in Oregon and 5,740 square miles (14,867 km 2) in Nevada, featuring a variety of land uses, including rangeland, wildlife habitat, irrigated pastureland and cropland, historic gold and silver mines, and active opal mines and ...
Interior of Amboy Crater showing a lava lake and the distant breach in the cinder cone rim. Interior of Amboy Crater from near breach showing lava lakes. Amboy Crater is a dormant cinder cone volcano that rises above a 70-square-kilometer (27 sq mi) lava field in the eastern Mojave Desert of southern California, within Mojave Trails National Monument.
Located on Jupiter's moon Io, the lava lake known as Loki Patera is a whopping 127 miles across and spans over 8,300 square miles — meanwhile, Lake Ontario covers just 7,320 mi².
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. [1] 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.
Four Craters Lava Field is a basaltic volcanic field located south east of Newberry Caldera in the U.S. state of Oregon. [1] The volcanic field covers about 30 square kilometers and post-dates Mount Mazama's eruption. [3] Four Holocene cinder cones are the source of the flows in the field and are aligned along a fissure trending N 30° W. The ...
The Columbia River Basalt Group (including the Steen and Picture Gorge basalts) extends over portions of four states. The Columbia River Basalt Group (CRBG) is the youngest, smallest and one of the best-preserved continental flood basalt provinces on Earth, covering over 210,000 km 2 (81,000 sq mi) mainly eastern Oregon and Washington, western Idaho, and part of northern Nevada.
