Figure 7. Photographs showing aspects of the Caetano caldera and Caetano Tuff. (A) View of Mount Caetano looking east. Mount Caetano is composed of densely welded lower unit of the Caetano Tuff that dips 40–45° east (away) from photo. Total topographic relief is 500 m. Remains of Caetano Ranch in foreground. (B) Strongly flattened crystal-rich pumice (fiamme) in densely welded basal vitrophyre in Caetano Tuff near Wenban Spring in northern Toiyabe Range. Hammer is 46 cm long. (C) View looking north of caldera margin in northern Toiyabe Range. Devonian Slaven Chert (Dsc) faulted against intracaldera Caetano Tuff (Tct) along the Copper Fault. Lens of mesobreccia in Caetano Tuff is enveloped by black vitrophyre thought to have formed by quenching of hot ash against cold breccia blocks shed into the caldera during eruption. (D) Flow bands in Carico Lake pluton. Hammer is 46 cm long.
