About this map

Mining operations and high-altitude infrastructure dominate this landscape at the western edge of the Tenmile Range. The map documents a significant industrial footprint within the mountains, centered on the massive Robinson Tailings Pond and Tenmile Tailings Pond. These features sit adjacent to the historic Kokomo (Site) and Kokomo, marking the remains of silver-and-zinc-era boomtowns that were gradually overtaken by large-scale tailings disposal from nearby molybdenum operations.

Tracing the complex water management required for these works, the survey identifies the Clinton Ditch and Fremont Ditch along the slopes of Carbonate Hill and Little Bartlett Mtn. Further north, legacy shafts like the Queen of the West Mine and Colonel Sellers Mine pepper the gulches below Jacque Ridge. This 1970 record captures the area as it transitioned from traditional hard-rock mining towards the modern industrial containment and recreation hub it is today.
