Deerlodge National Forest dominates this landscape in Jefferson County, where the high mountain terrain meets the wide alluvial expanse of the Boulder Valley. The map documents a significant intersection of drainage systems and resource extraction, with numerous unnamed prospects and a named mine situated in the north near Tacoma Gulch. The presence of tailings and scattered prospect pits across the eastern slopes of the forest suggests a legacy of mineral exploration that persists alongside natural features like Tacoma Spring and Deadman Spring.
