West Side Road:
Split Cinder Cone
A small volcanic cinder cone is located near the intersection of Highway 178 and the southern end of the West Side Road. This volcano erupted in the middle Pliestocene along the Southern Death Valley Fault zone (Hildreth, 1976; Spear, 2010). After the eruption, the volcano has gradually split along a strike-slip fault (the western, larger remnant of the cone has moved several hundred feet north relative to the smaller remnant on the east side of the fault). The cone has be right-laterally offset by about 300 feet. (USGS)
Split Cinder Cone Geology
Due to this site’s central location in Death Valley’s south end, this is a good place to view both
the Panamint and Black Mountains from a distance and to get a sense of the “pull-apart” tectonic origin of Death Valley itself.
