USGS Topo · Published 2012About this map
The Great Southern Overland Stage Route of 1849 carves a historical path through this desert corridor, marking a significant mid-19th-century transit line. At Scissors Crossing, the route intersects with modern infrastructure near the base of Sentenac Mountain. The landscape is defined by wide desert basins like San Felipe Valley and Earthquake Valley, separated by the steep rises of Grapevine Mountain and Granite Mountain.
