The geology of Sand Canyon, California


Carr, Robert Bradwell (1938) The geology of Sand Canyon, California. Bachelor's thesis, California Institute of Technology.


The area investigated lies in the western end of the San Gabriel Mountains in southern California, embracing the upper portion of Sand Canyon, a tributary of Soledad Canyon and the Santa Clara river. Parts of sections 4, 5, 6, 7, 8, 9, T3N, R14W; sections 1, T3N, R15W; sections 36, T4N, R15W are included in the area.

It is easily reached by travelling north from Los Angeles to Saugus, thence east on State Highway #6 to the Soledad Canyon road, about 8 miles. About 2 miles along this road is the Sand Canyon road which should be followed to the south to Bear Canyon, roughly the western end of the area, which lies as a rectangle 4 by 1 miles in size with the longer direction in an east-west direction.

The field work was done by mapping on the Sylmar and Little Tujunga Quadrangles of the U.S. Geological Survey, each of which has a scale of 1:24,000 and a contour interval of 25 feet. Location in mapping was done with a Brunton Compass.

The work was undertaken in connection with prospecting for ilmenite being done by E.I. du Pont de Nemours and Company, and the writer wishes to express his deepest thanks to Dr. J.L. Gillson and to Dr. George H. Anderson for permission to publish the paper and also for their invaluable assistance and direction.
