1959 Map of Sweeney Pass

USGS Topo · Published 1985

About this map

The Mountain Palm Springs Area and its clustered desert oases define this late-1950s survey of the Colorado Desert. The landscape is marked by a series of distinct groves including Marys Grove, North Grove, and Palm Bowl Grove, which follow the drainage patterns of Indian Canyon. The historic Old Overland Stage Route crosses the northeast corner, illustrating the path of early transportation through the Carrizo Badlands. Farther south, the transition between the Jacumba Mountains and the Volcanic Hills highlights a complex geological environment where industrial activity is noted at the Mortero Mine and a nearby Quarry. Local park management is established at the Bow Willow Ranger Sta, overseeing a terrain that includes the Smoke Tree Forest and the steep passage at Sweeney Pass.
