About this map

The high peaks of the McCullough Range dominate this desert landscape, featuring several prominent summits including a peak labeled Hanna. The terrain transitions sharply to the east into the broad expanse of the Eldorado Valley, an area increasingly defined by the infrastructure of regional energy transmission. A complex network of transmission lines and a dedicated Substation mark the valley floor, alongside a protective levee system. This late-twentieth-century survey reveals the area as a corridor for utility development, where modern power grids intersect with older geographic markers like Emblem. The map's detail provides a clear view of how high-voltage transit corridors were mapped across the basin floor, contrasting with the steep, undeveloped contours of the mountain range to the west.
