A 1:75,000-scale, color geologic map of the 34 Ma Caetano caldera, Lander and Eureka counties, Nevada with descriptions of 41 geologic units and one cross section. Accompanying text includes full unit descriptions and references. More than 100 percent extension beginning in the middle Miocene tilted the caldera into a set of about 40-degree east-dipping fault blocks that provide exceptional exposures of the entire caldera to its floor, including Paleozoic sedimentary rocks and pre-caldera volcanic rocks in the floor, intracaldera Caetano Tuff up to 4 km thick, ash-flow tuff feeder dikes, caldera collapse breccias, post-collapse resurgent intrusions, and the caldera structural margin and topographic wall.
