About this map

Engineer Mountain dominates the center of this San Juan high-country landscape, where the 1960s terrain is marked by a complex system of water management and high-altitude transit. An Aqueduct, Flume, and Siphon follow the contours of the mountain slopes above Cascade Creek, illustrating the infrastructure required to move water through this vertical environment. Further south, the map reveals the small-scale settlement at Harris Ranch along the East Fork Hermosa Creek, providing a rare point of private habitation within the broader San Juan National Forest.

Transportation through the region is defined by the steep ascent to Coal Bank Pass and Coal Bank Hill, with recreational and administrative outposts like Mill Creek Lodge, Columbine Ranger Sta, and the Lime Creek Campground serving as hubs for those navigating the peaks. From the heights of Jura Knob to the level expanse of Purgatory Flats, the survey documents a landscape used for both rugged transit via the Highline Trail and seasonal resource management.
