1981 Map of Groan Canyon

USGS Topo · Published 1981

About this map

The Sheepshead Mountains dominate this high-desert landscape in Malheur County, where a network of seasonal water sources supported ranching operations in the late 1970s. The map illustrates a rugged topography defined by deep drainage systems like Groan Canyon and Mickey Canyon, punctuated by essential water points such as Rock Corral Spring and Little Hole Spring. Small-scale water management is evident through several named catchments including Stoddart Reservoir, Hub Reservoir, and Red Line Reservoir, which suggest the vital importance of water rights and livestock grazing in this arid region of Southeast Oregon.
