From Wikipedia, the free encyclopedia

The Tumble Buttes are a group of cinder cone volcanoes in the US state of California.

Geography

[edit]

The Tumble Buttes are formed by three pyroclastic cinder cones: Bear Wallow Butte, Eiler Butte, and Hall Butte. They range in elevation from 6,391 feet (1,948 m) to 7,188 feet (2,191 m).[1] The volcanoes trend north-northwest to south-southeast along a fissure. Eiler Butte marks the northern end, while Bear Wallow Butte is the southernmost cone.[1]

Eruptive history

[edit]

The Tumble Buttes last erupted between 10,000 and 15,000 years ago, making them either Pleistocene or Holocene in age. The cinder cones have erupted lava flows.[1]

Geology

Subfeatures

[edit]

Bear Wallow Butte has unvegetated lava flows on both its eastern and western flanks; Eiler Butte has produced blocky lava.[1]
