2011 Map of Monument Hill

About this map

Mineral Wonder Gulch and Fassbinder Gulch highlight a landscape defined by its mining history, where numerous lode claims and prospects dot the mountainous terrain of La Plata County. This 2011 survey illustrates the complex drainage network feeding into Hermosa Creek and Junction Creek, with high-altitude features like Olga Little Mountain and Monument Hill providing significant vertical relief. The map documents the enduring infrastructure of the San Juan region, from the Kennebec Mine in the west to the Last Chance Mine in the east. Scattered throughout the drainage basins are specific sites of interest to local historians, including Cemetery Flats near Cape Horn and the uniquely named At Last Ranch situated along the lower reaches of Falls Creek.
