| Looking eastward to the western slopes of the Inyo Mountains along the route to Union Wash. The reddish-brown rocks along the middle and upper ground belong to the Lower Triassic Union Wash Formation (lower slopes) and the Permian Lone Pine Formation of the Owens Valley Group (which yields fusulinids, corals, crinoids, brachiopods and molluscan material farther south in the Darwin area, just west of the Death Valley National Park boundary). Darker rocks seen near the crest of the Inyo Range consist of limestones of the Pennsylvanian Keeler Canyon Formation (bears abundant fusulinds and crinoidal debris). |
