1898 Map of Engineer Mountain

USGS Topo · Published 1955

About this map

San Juan Mountains high country dominates this late 19th-century survey, revealing a landscape defined by the extraction and transport needs of the Silverton district. The Denver and Rio Grande RR (Silverton Line) hugs the banks of the Animas River in the east, passing Cascade Siding and a specialized Power House near Reservoir No 3. This early infrastructure supported the burgeoning industrial activity of the region, where water management was critical, as evidenced by the Flume near Purgatory.
