For my M.S. research with Professor Elizabeth L. Miller at Stanford University, I produced a thesis titled Geology and geochronology of Cenozoic units in the Piñon Range and Huntington Valley, Nevada. This document contains data and descriptions that weren't published by Lund Snee and Miller (2015) and Lund Snee et al. (2016), so I include it here.
The figure shows four views of the tuff of Dixie Creek, a succession of Eocene ignimbrites deposited rapidly and thickly in the eastern Piñon Range. These rocks provide an important, precisely dated constraint on the timing of local, faulting-related tilting and regional, southward-sweeping volcanism. Pumice lumps of different compositions are shown in C and D.
