on Mt Wilson that is six miles by path to the N.E., but as the crow flies is not more than two miles. Mount Lowe is one of the peaks of the San Gabriel Range, and it rises sharply out of the valley onto Caltadena near the fault trace. To the S.W. are the Santa Monica granitic outcrops and between lies the dilly plain made up of Pliocene-Pleistocene strata. To the east of the Santa Monica Mts lies the Los Angeles Plain of the same strata but of another seaway. These E-W Mts are all fault blocks that arose (later?) in the Oligocene and made the two sea ways mentioned. Most of the elevation appears to have taken place during the Pleistocene but may have begun during the Pliocene. Some of the peaks in the San Bernardino Mts must be more than 9000 feet high. While on the top of Mount Lowe it cleared a little. Quickly the crowd changed for the east, and the skies began to cloud up once and once.
