About this map

Platoro sits at the heart of this high-elevation landscape, where the Conejos River meets the waters released by the Platoro Dam. The surrounding mountains are marked by a significant mining legacy, with numerous claims clustered east of the reservoir. Notable sites include the Siskiyou Mine, Glacier Mine, and the Mammoth Revenue Mine, reflecting the intensive prospecting history of the eastern slopes. To the south, the terrain rises toward Conejos Peak, overlooking a network of alpine basins containing Tobacco Lake, Twin Lakes, and Bear Lake.

The presence of Shortys Cabin and the Mix Lake Campground points to the area's continued importance for seasonal habitation and backcountry access via the FS RD 250. The map documents a landscape defined by dramatic drainage patterns, from the deep Cañon Diablo to the headwaters of the Alamosa River near Stunner Pass, providing a clear record of the intersection between industrial mineral extraction and the high-country hydrology of the southern San Juan mountains.
