AVO geologist M. Loewen (right) discussing eruption dynamics of the Fisher caldera forming eruption with UAF geologist P. Izbekov (middle) and AVO geologist C. Waythomas (left). The ignimbrite from the Fisher caldera forming eruption is the top, thick unit M. Loewen is pointing at, and the airfall deposit associated with it is immediately below. This airfall is easily recognized by its black basal pumice and lighter cream colored pumice immediately on top.
