About this map

Angeles National Forest dominates this 1931 survey, characterized by the sharp topographic relief of the Sierra Pelona Mountains before major modern development. The map, produced under County Surveyor J. E. Rockhold and Chairman Henry W. Wright, captures the intricate drainage patterns of the region, where Elizabeth Lake Canyon and Sawmill Canyon carve through the high-elevation terrain. This advance sheet serves as a primary record of the watershed and mountain peaks such as Burnt Peak and Lookout Mountain during the early decades of the forest's management.

The presence of Warm Spring in the southern portion of the quadrangle highlights the critical water sources that defined land use and early navigation in these steep canyons. At this time, the landscape was largely defined by its natural features and surveying lines, including the township boundaries of T. 7 N. and T. 6 N., with very few man-made structures or roads recorded beyond the primary canyon floor routes.
