Geology of Tick Canyon


Bonillas, Ygnacio, III (1933) Geology of Tick Canyon. Bachelor's thesis, California Institute of Technology. doi:10.7907/GCCT-S998.


Tick Canyon lies in the north central portion of the Lang quadrangle, Los Angeles county, California. It is about twenty-five miles northwest from Pasadena as the crow flies, but fifty miles by the most direct roads. The area is easily reached by driving two miles east from the Mint Canyon highway on a road six miles north of the Santa Clara river.

Approximately three square miles were studied. The area is roughly rectangular, extending north and east of the head of Tick Canyon. The investigation was undertaken as a partial fulfillment of the requirement leading to the degree of Bachelor of Science at the California Institute of Technology. As a base map a Los Angeles county map surveyed in 1929 and published in 1933 was used. This has a scale of two-thousand feet to the inch and twenty-five foot contour intervals. It is very satisfactory and makes detailed work possible.

The author wishes to acknowledge his indebtedness to Dr. John H. Maxson of the Institute staff, and to thank him for his aid and for his fruitful suggestions, which have made the work possible.

This region was previously described by Dr. William S.W. Kew in Bulletin 753 (1924) of the United States Geological Survey.

A description of the area was also published by Mr. O.H. Hershey: Am. Geologist, vol. 29, pp. 356-358, 1902.
