1960 Map of Engineer Mountain

About this map

Engineer Mountain and the high alpine ridges of the San Juan National Forest define this 1960 survey, which captures the area before modern recreational development intensified. The map documents a landscape of high-altitude passes and remote outposts, including Coal Bank Pass and the Columbine Ranger Sta. In the valleys, scattered landmarks like Harris Ranch and the Mill Creek Lodge suggest early ranching and seasonal hospitality. A complex network of drainage systems, such as Lime Creek and the East Fork Hermosa Creek, feeds into small high-country basins containing Potato Lake and Boyce Lake. Industrial and transport traces are visible through a Gravel Pit, an Aqueduct, and the rugged Highline Trail, showing how the era's infrastructure contended with the steep topography of the San Juan Mountains.
