Berkeley, Tuesday, Feb 22 George Washington's first day, and a bright day it is, that some mist is in the air coming in from the Pacific. Worked all day with Clark on my paleo- geographic maps. They are tallying on a changed loot and especially in the vanishing of the Bride land. Will finish tomorrow. See notes elsewhere. At 3.30 Clark took me on his Ford over the Berkeley Hills to see two of the fault valleys and several of the faults' throats. All of the shores are much folded and often crumpled in play due to movement near the fault zone. San Franciscan, Cretaceous and much of Cenozoic. The top side down of the hills is two large fault scarps. These hills are filled with dunes and many flood stream beds. Some is paying attention to the nature of the ground and many dunes are built on a fault zone that may form aggravated 17 feet. The most fascinating.
