1966 Map of Horse Gulch

About this map

The Yampa River carves a winding, serpentine path through northwestern Colorado in this mid-1960s survey, illustrating the complex hydrology of the high plateau country. The river serves as the central focal point, flanked by dramatic elevations such as Signal Butte and the towering heights of Duff Mountain. This area represents a rugged ranching landscape where isolated settlements like the Culverwell Ranch and seasonal Springs define the human footprint. To the south, the terrain opens into the Axial Basin, a significant geographic depression that contrasts with the surrounding dissected plateaus. The map documents a dense network of drainage systems, including Horse Gulch, Sand Gulch, and Morgan Gulch, which channel snowmelt toward the Yampa. These named features, along with various Jeep Trails, reveal a remote territory where access was primarily dictated by topography and the needs of local livestock operations.
