1992 Map of Obsidian Butte

USGS Topo · Published 1995

About this map

Salton Sea dominates the landscape of this Imperial County quadrangle, where the water's surface sat at an elevation of 228 feet below sea level at the time of the 1992 revision. The map reveals the intricate water management system required for the surrounding basin, defined by a dense network of irrigation channels including Vail 6 Drain, Vail 7 Drain, and several Lateral branches. A prominent geological landmark, Obsidian Butte, rises along the southeastern shore, providing a rare point of topographical relief in the low-lying desert.
