DEPOSIT AT MOUTH OF SESPE CANYON. At one point overlooking Sespc Creek there is a cut bluff showingbright-red sediments of apparently the same materials as those justdescribed. The deposit was not examined in detail. It may proveto be a remnant of the Sespe formation or a portion of the Pleistocenethat is composed of red material derived from the Sespe. CONGLOMERATE OF LION CANYON. In the vicinity of the Lion Canyon wells is a conglomerate that hasnot hitherto been recognized at any point in the Ojai Valley, nor,indeed, elsewhere in the ranges that border the Santa Clara.
