2022 Map of Engineer Mountain

About this map

Engineer Mtn stands as a central focal point within the high-elevation reaches of the San Juan National Forest, where the borders of San Juan, Dolores, and La Plata counties converge. This survey documents the complex network of trails that define mountain transit, including the Engineer Mountain Trl and the historic Rico-Silverton - Co Trail Trl. The landscape is defined by its dramatic verticality, from the broad Hermosa Park and Purgatory Flat in the south to sharp peaks like Jura Knob and Grayrock Peak in the north. Water drainage patterns are clearly established by Cascade Cr and Lime Cr, which carve through the terrain near landmarks like Coal Bank Pass and Coal Bank Hill. These features, along with several high-altitude lakes such as Potato Lake and Scout Lake, illustrate the geography of this part of the San Juan Mountains.
