WebNov 20, 2011 · Our current working hypothesis — our current best model — comes from a paper by Wes Hildreth and Colin Wilson on the Bishop Tuff eruption. The Bishop Tuff is the deposits from an eruption that produced at least 600 km 3 of magma and created the Long Valley Caldera in California 2! They used this, along with information on the smaller ... WebThe Glass Mountain eruptions, which were fed by a large, chemically evolving magma chamber in the shallow crust, culminated in the cataclysmic eruption of 600 cubic kilometers of high-silica rhyolite 760,000 years ago. This massive eruption resulted in the widespread deposition of the Bishop Tuff and the simultaneous 2- to 3- km subsidence …
