Descend into wash and park north off road. Walk to Cave Mountain gravel is exposed along the east side of the wash. Characteristic deposits in this area consist of gray massive to well-bedded, moderately sorted sand that is arkosic in composition, alternating with conglomerate made up of clasts from Cave Mountain granite. Both rock types are carbonate cemented to a degree, the conglomerate generally more strongly cemented. A moderate hike up the wash and then east along the north side of this hill provides much better exposures of the gravel unit, especially its interesting sand intervals.
