Introduction
The Big Cave shield volcano, at the northern end of an area of late-Quaternary volcanism extending north from Lassen Peak, is a small basaltic shield with young pyroclastic cones at the summit and north flank. Big Cave volcano was considered to be of either Holocene (Luedke and Smith, 1981; Miller, 1989) or latest Pleistocene or Holocene age (Sarna-Wojcicki et al., 1983). The inconspicuous low shield volcano, located between Big Lake on the north and Bald Mountain on the south, is surrounded by an extensive now forested lava field. Big Cave was considered by Clynne, 2007 pers. comm.) to probably be of similar age as nearby Cinder Butte volcano, which was dated at 38,000 +/- 7000 years.---
