Geology of a Portion of the South Side of the Santa Clara Valley Near Newhall, California


Hagen, Robert Christian (1939) Geology of a Portion of the South Side of the Santa Clara Valley Near Newhall, California. Bachelor's thesis, California Institute of Technology. doi:10.7907/ZS18-YW90.


The area is located between the foot of the San Gabriel Mountains and the Santa Clara River and is about four miles east of Newhall and Saugus, California. It is about thirty-six miles north of Los Angeles, California.

The area is approximately two by two and a half miles in size and contains about five square miles. It is bounded on the north by the Santa Clara River; on the east, by the area worked by John A. Battle; on the south, by the San Gabriel Mountains and Placerita Canyon; and on the west, by Longitude 118 28'.

The area is conveniently reached by one of two roads. The side to the north is reached from the Palmdale-Los Angeles State Highway which runs along the northern boundary. Someday this highway will pass through the area. From this highway, dirt roads lead towards the center of the area, passing through the valleys draining into the Santa Clara River. The south side is entered by means of the Placerita Canyon Road which turns off just north of the outskirts of Newhall. This road is paved part way, but is dirt the rest of the way. It is, however, passable, and makes it easy to get into the southern end. From this road, the center of the area can be reached by hiking up abandoned roads and trails. No part of the area is more than one mile's hike to reach.
