The Bishop Tuff is a welded tuff which formed 764,800 ± 600 years ago as a rhyolitic pyroclastic flow during the approximately six-day eruption that formed the Long Valley Caldera. [1] [2] [3] Large outcrops of the tuff are located in Inyo and Mono Counties, California, United States. Approximately 200 cubic kilometers of ash and tuff erupted ...
The southeastern slope from the caldera down towards Bishop, California, is filled with the Bishop Tuff, solidified ash that was ejected during the eruption that created the caldera. The Bishop tuff is 1,500 metres (4,900 ft) thick in the caldera floor, [3] and is cut by the Owens River Gorge, formed during the Pleistocene when the caldera ...
