Two layers of the Bishop Tuff: lower layer was from ashfall, upper layer was from the main pyroclastic flow.
The 'Bishop Tuff' is located in the
Owens Valley, southeast of
Mammoth Lakes, California. It is a
welded tuff that formed 760,000 years ago as a rhyolitic
pyroclastic flow during the eruption that created the
Long Valley Caldera.
The ''Bishop Tuff'' covers nearly 2,200
square kilometers of area, with deposits ranging from 150 to 200
meters in thickness.
