Pipkin (also known as Malpais Crater [1]) is a volcano in California, with activity during the Quaternary. [2] The surface of erupted lava flows is weathered, and argon-argon dating and potassium-argon dating has yielded ages of 770,000 ± 40,000 and c. 600,000 years before present, respectively. [3]
The volcano lies in the Rodman Mountains. [4] The 300 feet (91 m) high and 2,000 feet (610 m) wide [5] Pipkin cinder cone probably erupted the lava flows which extend to its north and form a lava flow field which has the appearance of a mesa. [6] The cone itself consists of lava bombs and scoria with red and black colours. [5] Lava flows from the vent propagated through Kane Wash [4] and into the Mojave River valley; [7] it is possible that the lava diverted part of the wash into neighbouring Sheep Springs Wash. [8]
The cone is the site of a quarry. Pipkin was mined since the 1950s for its ash. [5]
