Closeup of alternating sandstone and conglomerate beds in the Santa Susana Formation along Rocky Peak Fire Road. Note that the conglomerate clasts are subrounded to subangular and that the beds grade upward (left to right) from conglomerate to sandstone, indicating a decrease in depositional energy during deposition of the paired graded beds. Each of the pairs might indicate storm deposition and the reduction of energy as the storm wanes.
