This is a list of active, dormant, and extinct volcanoes located beyond planet Earth.They may be designated mons (mountain), patera (an irregular crater) or tholus (small mountain or hill) in accordance with the International Astronomical Union's rules for planetary nomenclature.
All of these volcanoes have been extinct for millions of years. [2] The Pilot Knob volcanic complex consists of four small, rounded hills (including Pilot Knob proper) forming the volcano's core area in an area two miles in diameter. The hills are composed of trap rock which is an erosion-resistant, fine-grained mafic volcanic rock.
Malheur Butte is an extinct volcano located in Malheur County, Oregon. Between 20 and 15 million years ago, the region from north-central Washington to northeastern California experienced a series of volcanic eruptions and basalt lava floods that covered thousands of square miles. These ancient lava floods often dammed streams, creating lakes ...
Black Buttes is an extinct volcano with an amphitheater shape. It consists of jagged peaks that form an arc-shaped ridge, which were shaped and altered by glacial motion and erosion. [12] Part of its amphitheater and its main eruptive crater is currently taken up by Deming Glacier, [12] the rest of the volcano sitting above the glacier. [13]
