Bishop Tuff, Volcanic formation in Inyo and Mono Counties, California, United States
The Bishop Tuff extends across a plateau of welded ash and pumice, displaying distinctive stone columns and wave patterns through erosion patterns.
The formation emerged 764,800 years ago during a six-day volcanic eruption that released 200 cubic kilometers of ash and created the Long Valley Caldera.
Geologists and researchers analyze the tuff layers extensively to understand volcanic processes and develop regional eruption prediction models.
The formation spans 2,200 square kilometers with deposits reaching 200 meters in thickness, accessible through roads near Crowley Lake and Bishop.
The Owens River cuts through the volcanic tableland, creating deep gorges that reveal distinct mineral compositions of biotite, plagioclase, quartz, and sanidine.
