About this map

Troy Lake and the arid expanse of the Mojave Valley dominate this High Desert landscape during the early 1980s. The map illustrates a harsh environment shaped by geological forces, evidenced by the expansive Lava flows spreading south from the Cady Mountains. Infrastructure in this remote stretch of San Bernardino County is sparse, characterized primarily by an underground gas pipeline and a series of levees designed to manage seasonal water flow toward the Dry Lake basins.

Evidence of human attempts to settle or extract value from the desert appears at Poe (Site) and various borrow pits. The presence of a Rest Area and scattered wells suggests this area served more as a corridor for transit and resource management than a residential hub. To the south, the foothills of the Rodman Mountains rise above Kane Wash, where the terrain shifts from the flat alkali basins of the Dry Lake to more complex alluvial fans.
