Background
The Lava Mountain lava field, also known as the East lava field or Squaw Ridge lava field, is the middle of a group of three young basaltic fields located in the High Lava Plains SE of Newberry volcano. In contrast to the small fissure vents of the adjacent Devils Garden lava field, the Lava Mountain field consists of a shield volcano capped by the Lava Mountain pyroclastic cone complex that forms a prominent topographic high. Lava flowed in all directions for distances up to 6 km from the summit cone complex. The age of the lava field is not known directly, but Lava Mountain is thought to have been formed during the same eruption as nearby Four Craters lava field (only 6 km away), whose vents share alignment along the regional fault system extending from Christmas Valley NNW to Quartz Mountain. Both lava fields have similar lava chemistry and paleomagnetic directions, and the Four Craters eruption was dated based on surface exposure evidence by Mackey et al. (2012) to 13 ka.---
