2015 Map of West of Palo Verde Peak

About this map

Milpitas Wash defines the drainage patterns of this arid landscape in eastern Imperial County, cutting through the terrain as it flows toward the Colorado River valley. The map documents the vast, open reaches of Smoketree Valley, a name that suggests the specific desert flora found within these dry alluvial plains. This 2015 edition reflects the modern cartographic state of the region, emphasizing the natural topography and the Public Land Survey System grid through townships such as t10s r19e and t9s r20e. The absence of developed townsites or major highways highlights the area’s character as an undeveloped desert corridor, where the land is primarily shaped by ephemeral watercourses and the natural slope of the basin.
