1982 Map of Grasshopper Flat South

USGS Topo · Published 1983

About this map

Grasshopper Flat and Hansen Flat dominate this high-desert landscape in southeastern Oregon, as documented by the U.S. Geological Survey during a 1979 field check. This provisional edition reveals a terrain defined by water management and natural springs in an otherwise arid expanse. Small catchments like Echave Reservoir, Rosio Reservoir, and Trail Creek Reservoir are scattered across the flats, likely serving livestock or wild horse populations. Named features like Juana Forty Spring and Maiden Spring suggest a history of human activity and ranching heritage, while unique geological markers such as Hole-In-the-Ground and the steep incisions of Big Antelope Creek provide essential navigational landmarks. The map traces the intermittent flows of Tenmile Creek and Little Rattlesnake Creek, illustrating the complex drainage patterns that converge near Arcade Field.
