Big Mountain dominates the southern landscape of this mid-1980s provisional study, overlooking the winding path of the Boulder River as it cuts through the valley floor. The terrain reveals a history of extraction and exploration, with numerous Mine Shafts and Prospects clustered near the namesake Willow Springs and across the high ridges. These labels indicate a landscape defined by small-scale mineral ventures rather than large industrial hubs.
