The Black Rock Desert volcanic field in Millard County, Utah, is a cluster of several volcanic features of the Great Basin including Pahvant Butte, The Cinders, and Tabernacle Hill. [1] The field's Ice Springs event was an explosive eruption followed by lava flows that were Utah's most recent volcanic activity (1140–1440 AD).
The Pahvant Butte volcano consists of an asymmetrical tuff cone with a breach on its southwestern side — and a platform area that extends to the southeast of the cone, formed of beds of tephra dipping steeply away from the cone, and partly concealing a mound of near horizontally-bedded sideromelane tephra beneath.
