on Mt Wilson that is six miles by path to the R.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 with Caltadena near the fault trace. To the S.W. are the Santa Monica granitic mts and between lies the valley plain made up of Pliocene - Pleistocene strata. To the south of the Santa Monica Mts lies the Los Angeles Plain of the same strata but of another sea way. These E-W Mts are all fault blocks that arose? late in the Pliocene 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 locos in the San Bernardino Mts must be over 9000 feet high. While on the top of Mount Lowe it shined a little. Quickly the crowd changed for the east and the sky began to cloud up more and more.
