2021 Map of Blue Mountain

About this map

The Chocolate Mountains dominate this 2021 topographic profile of northeastern Imperial County, California, showing the complex landforms and dry washes that characterize this arid upland. The map centers on the high points and ridgelines of the range, including the prominent summit of Blue Mtn in the northwestern corner. Produced by the U.S. Geological Survey, this study provides a clear view of the Public Land Survey System divisions, including sections within t11s r18e, t11s r19e, t12s r18e, and t12s r19e. The absence of roads or settlements emphasizes the desert character of this terrain, where the focus remains on the precise contouring of the peaks and the natural drainage patterns of the desert floor.
