Red Hill

Red Hill (3952’) is a volcanic cinder cone that has been extensively mined for cinders used as aggregate in concrete and cement blocks. Some years ago, local citizens made a successful effort to save the Red Hill from complete destruction by limiting mining to the side hidden from the road. Volcanism continues underground to this day in the Coso volcanic field nearby. A geothermal plant east of the town of Coso Junction takes advantage of this free energy source.
