Sulphur Spring Range dominates the central landscape of this 1937 survey, where a high-desert mining and ranching economy is visible through its network of isolated outposts and springs. The settlement of Mineral Hill and the Old Whalen Mine highlight the era's subterranean extraction, while family-named holdings like the Plummer Ranch, Bruffey Ranch, and Alpha Ranch define the valley floors.
