About this map

Little Grassy Mtn and Black Butte anchor this high desert landscape in southeastern Oregon, where water management is the primary imprint on the land. The map reveals a sophisticated network of small-scale irrigation and stock water catchments, including Little Grassy Reservoir, Greeley Reservoir, and Plateau Reservoir. These features, along with Hole in Ground, illustrate the vital importance of seasonal water storage for ranching operations in a region defined by arid flats like Rock Creek Flat and Antelope Flat.

Transport is limited to long-established backcountry routes such as Three Forks Rd and the Grassy Mountain Loop, which navigate around the dramatic drop-offs of Owyhee Canyon. The terrain transitions from the high vantage points of Juniper Ridge to the drainage basins of Spring Cr and Soldier Cr, showing a landscape where geographic features are often named for the early settler families who managed the reservoirs and rangelands.
