The Geology of Mount Washington

Abstract

The scope of this report embodies the work done in an area of six and a half square miles in extent, which lies between the northern portion of Los Angeles and Highland Park, more specifically it is bounded on the north by the 34°07' parallel of latitude, on the south by the 34°5'30 parallel of latitude, on the west by the 118°14' meridian of longitude, and on the east by the 118°12' meridian of longitude. The United States Geological Survey have made excellent topographic maps of this area on the scale of 1/24,000 with a contour interval of 25 feet on the more prominent topography and 5 foot contours on the more subdued portions. The area is covered by the southeast corner of the Glendale Quadrangle and the northeast corner of the Los Angeles Quadrangle. Mount Washington is easily reached from any of the near by cities, Los Angeles, Pasadena, Glendale, Alhambra, by excellent paved highways. Not only do good highways lead to these hills but nearly all points in this region are accessible by automobile roads.
