The High Lava Plains ecoregion is a vast, nearly level to undulating sagebrush steppe containing scattered volcanic cones and buttes. Elevation varies from 4,200 to 6,800 feet (1,280 to 2,073 m). Elevation varies from 4,200 to 6,800 feet (1,280 to 2,073 m).
The Brothers Fault Zone is also the locus of the High Lava Plains (HLP) volcanism of central and southeastern Oregon. HLP volcanism is notable for showing an age progression from 16 Ma at its eastern end (near the Oregon–Nevada–Idaho corner) to the active Newberry Volcano at its western end.

Newberry lies 37 miles (60 km) east [9] of the major crest of the Cascade Range in the High Lava Plains region, [7] rising 3,500 feet (1,100 m) above its surroundings. [3] From north to south, the volcano runs for a length of 75 miles (121 km), with a width of 27 miles (43 km) [7] and a total volume of about 140 cubic miles (600 km 3). [9]
The basin is part of the High Lava Plains, a region dominated by erupting volcanoes in the late Miocene, five to ten million years ago. Centered on the Brothers Fault Zone, which runs southeast–northwest between Steens Mountain and Bend, the High Lava Plains merge with the Blue Mountains to the north and the Basin and Range Province to the ...
Many geological features in Western United States have a Northeastern orientation, the North American craton motion has the same orientation as well. [1] For example: the Trans-Challis fault zone, Idaho; the Snake River in Oregon; the Garlock Fault, California; the Colorado River in Utah; the Colorado Mineral Belt; Crater Flat-Reveille Range-Lunar Crater lineament, the Northwestern Nevada ...
The lava has mostly flowed east from the eruption site, but there is also a lava tongue flowing west from the region north of Stóra-Skógfell. (Icelandic Met Office) Hazard map updated as risk of ...
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.
