Sediments of the Imperial and Palm Spring Groups north of the Coyote Mountains are deformed by the recent uplift of the range. Brittle and ductile deformation of sediments in this area is consistent with prior interpretations of uplift and inversion of the Fish Creek-Vallecito basin as a result of initiation of the Elsinore and other strike-slip faults in the western Salton Trough ~1.2 Ma (Dorsey et al, 2011). Continued right-lateral strike-slip motion on the Elsinore fault is accommodated by a network of ladder-like faults known as the Andradé ladder structure. This ~7-km-wide fault structure is consistent with a zone of distributed right-lateral shear and rotation that accommodates the right-lateral deformation between the Elsinore and Painted Gorge faults.
