The Marysvale contains a variety of volcanic features, including stratovolcanoes, calderas, lava domes, and cinder cones. The field is an example of intraplate volcanism ; its earlier deposits are thought to be related to Farallon plate subduction , while the later bimodal assemblage (especially the basalts) have been linked to Basin and Range ...
A gap in the geologic record following deposition of the Claron Formation was interrupted 34 to 31 mya by eruptions from the nearby Marysvale volcanic field, which is located northwest of the park. [ 11 ] [ 12 ] Volcanic ash and lava from these flows are found less than 20 miles (30 km) from Bryce Canyon but at least some volcanic material was ...

Mount Belknap is set in the Fishlake National Forest on the boundary that Beaver County shares with Piute County. [2] It ranks as the second-highest peak in the Tushar Mountains, [3] second-highest in each county and 73rd-highest in the state. [1] Precipitation runoff from the mountain drains into the Sevier River watershed via Blue Lake Creek ...
Little is known about the history of the oldest exposed rocks in the area due to extensive metamorphism.This somber, gray, almost featureless crystalline complex is composed of originally sedimentary and igneous rocks with large quantities of quartz and feldspar mixed in. [1] The original rocks were transformed to contorted schist and gneiss, making their original parentage almost unrecognizable.
On March 27, 1980, a series of volcanic explosions and pyroclastic flows began at Mount St. Helens in Skamania County, Washington, United States. A series of phreatic blasts occurred from the summit and escalated until a major explosive eruption took place on May 18, 1980, at 8:32 am. The eruption, which had a volcanic explosivity index of 5 ...
