Abstract

As a partial fulfillment of the requirements in obtaining a degree of Master of Science in Geological Sciences at the California Institute of Technology, the writer was given the task of writing a thesis on the following subject: “Magnetic Survey and interpretation of the results over the San Gabriel wash.”

The area is between Monrovia and Azusa, two miles west of Azusa. It is accessible by several roads branching from Foothill Boulevard (U.S. Highway 66) running east and west, passing through Monrovia and Azusa. One of them is the Las Lomas Road going north along the west bank; the other one is an oiled road going to the Cyanide Company plant and continuing as a dirt road along the east bank. The upper part of the wash and the canyon itself can be reached by the State Highway 39 running northward from Azusa. From this road several dirt roads branch out.

The wash is too large to make a detailed survey in a short time. Thus, the work done is more or less a reconnaissance survey. It is surrounded by farms, the Cyanide Company plant, private properties and impenetrable jungle-like areas, so that it has not been possible to take readings anywhere. Another disadvantage is that the running water is controlled by the dam, and sometimes it cannot be crossed, due to abundance and speed of water. Big granite boulders covering the whole wash constitute still another disadvantage, making tripod setting very difficult.

The work was carried on under the directions of Dr. G.W. Potapenko, Associate Professor of Physics, whose assistance is gratefully acknowledged by the writer.
