Description: From Nye and Turner (1990): "Riehle (1985) reports a minimum age of basal Crater Peak (including proto-Crater Peak) tephra of 6000 years. The Mt. Spurr and the Crater Peak/proto-Crater Peak complex were, in part, coeruptive."

From Riehle (1985): "The oldest tephra layers assigned to the Crater Peak vent are loosely bounded by the available data to a middle Holocene age (sites 13 and 14; Fig. 11; site 20, Fig.12 [in original text])."
