The Ubehebe Crater Field consists of Ubehebe Crater (2,500 ft or 760 m across and 600 ft or 183m deep), Little Hebe Crater Crater (>300 ft or 91 m wide) to its south, and a cluster of smaller craters to their west. There are 14 craters within 1 square mile (2.6 square km) with tephra blanketing a large area. The eruption took place about 2,100 years ago and likely lasted days to months (Miller, 2024).
The craters are mostly maars, formed as a plume of basaltic magma rose toward the surface and encountered ground water and produced a large volume of steam. When the steam pressure can no longer be contained by the rock strata a violent explosion occurred producing the maar crater. This process likely proceeded in pulses. It results in only a tephra eruption with no lava flows.
Layers of tephra are visible in the upper crater walls, overlying the alluvial material it blasted through seen deeper inside. Small playa deposits have accumulated within various craters, too.
