1959 Map of Earthquake Valley

USGS Topo · Published 1987

About this map

The Old Overland Stage Route cuts a diagonal path across this desert landscape, tracing a historic transportation corridor through the eastern San Diego County mountains during the late 1950s. This survey centers on the intersection of travel ways and rugged geology, notably at Scissors Crossing where the valley floor transitions into the heights of Grapevine Mtn and Sentenac Mtn. The presence of the San Felipe-Butterfield Stage Station Historical Marker underscores the area's significance as a former lifeline for Western mail and passengers.
