Abstract

The Echo Hills is a distinctive area of tectonic uplift and shortening located at a right step in the left-lateral Bitter Spring Valley fault of the late Tertiary Lake Mead fault system, Nevada. The fundamental internal structure of the Echo Hills is an asymmetric anticline disrupted by reverse and oblique faulting. An analysis of the stress distribution within the stepover indicates that the interaction between the two segments of the Bitter Spring Valley fault is responsible for the compressive deformation and structural uplift in the Echo Hills. Given the number of strike-slip faults in the Basin and Range, similar examples of Tertiary uplift and shortening probably occur elsewhere within the province.
