The Hatch 7.5 minute quadrangle lies along the Sevier River Valley between the eastern edge of the central Markagunt Plateau and the western Paunsaugunt Plateau. Exposed stratigraphic units range from Late Cretaceous to Holocene in age and consist dominantly of tuffaceous sedimentary strata with minor basalt, ash-flow tuff, and air-fall tuff. The oldest exposed unit is the Straight Cliffs Sandstone, which is exposed in the footwall of the Sevier fault. Younger units include terrigenous clastic and carbonate strata of the Oligocene Brian Head Formation, ash-flow tuff of the Oligocene Isom Formation, and a heterogeneous assemblage of dominantly volcaniclastic fluvial and lacustrine strata, herein formally named the Limerock Canyon Formation.
