1985 Map of East of Dale Lake

USGS Topo · Published 1985

About this map

The Sheep Hole Mountains dominate the western portion of this mid-1980s topographic record, rising abruptly from the surrounding desert floor. This 1985 survey, based on aerial photographs from 1977 and field checks from 1978, illustrates a landscape defined by dramatic elevation changes and dry wash systems that extend across the boundary of R 13 E and R 14 E. The map's contour lines reveal the intricate canyons and ridges of the mountain range, while the vast desert expanse to the east shows the characteristic alluvial patterns of the San Bernardino County interior. As a provisional edition, this document represents the primary surveying data available at the time, focusing on the natural geomorphology and the survey grid rather than man-made infrastructure.
