PLEISTOCENE DEPOSITS. 
DEPOSITS IN THE VICINITY OF SAUGUS. 
The low hills that border the broad, open valley of Santa Clara 
River in the vicinity of Saugus are covered by a prominent body of 
gravel, sand, and arenaceous clay, the gravel largely predominating. 
The coarser material is mostly composed of granite, derived, prob¬ 
ably, from the San Gabriel Range. Traces of other rocks, however, 
are included with the granite, and the whole is loosely cemented 
together. The beds have a general dip of 2° to 10° toward the center 
of the valley. The thickness of the terrane is undetermined. Above' 
the level of the valley perhaps 300 or 400 feet are exposed, but below 
the valley the extent of the formation is not known. These beds 
are probably of fresh-water origin and, though they have yielded no 
fossils whatever, their unconformable position on the Fernando sug¬ 
gests late Pleistocene as the time of their deposition. 
DEPOSIT AT MOUTH OF SESPE CANYON. 
At one point overlooking Sespe Creek there is a cut bluff showing 
bright-red sediments of apparently the same materials as those just 
described. The deposit was not examined in detail. It may pro ve¬ 
to be a remnant of the Sespe formation or a portion of the Pleistocene 
that 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 has 
not hitherto been recognized at any point in the Ojai Valley, nor, 
indeed, elsewhere in the ranges that border the Santa Clara. Its
