1964 Map of Groundhog Reservoir

USGS Topo · Published 1968

About this map

Groundhog Reservoir serves as a focal point for this mid-1960s survey of the high country within the San Juan National Forest. The landscape is defined by its complex water management and storage, featuring smaller catchments like the Old Dunham Reservoir, North Nipple Reservoir, and Saddle Reservoir, alongside a network of irrigation works indicated by several Ditch labels. This infrastructure suggests the area's importance for regional livestock or agricultural needs despite the high elevation. Settlement is minimal, represented by the isolated Lavender Sch in the northwest, which provided schooling for families in the remote drainage of Disappointment Creek. The terrain transitions from the heights of Flattop Mountain and the Rincon down to meadows and basins like Boggy Basin, accessible only by Trail or Jeep Trail, illustrating the rugged, utilitarian nature of these mountain allotments.
