2017 Map of Round Top Butte

About this map

Round Top Butte dominates this high-desert landscape in Harney County, rising above a network of seasonal water sources and specialized agricultural infrastructure. The terrain is defined by its drainage patterns, notably the Sinks of Lost Creek where Lost Cr disappears into the earth. Throughout this arid section of the Oregon outback, early 21st-century land use is marked by a series of critical water management features, including the Lost Cr Reservoir, N Sheep Mountain Reservoir, and W Sheep Mountain Reservoir. Small natural catchments like Pasture Lake and Anderl Lake sit alongside reliable groundwater points such as Bradley Spring, Skookum Spring, and Dolton Spring. The presence of the Manoeuvre Road Reservoir and the rugged Hay Lk Deep Valley reflects a landscape managed for grazing and remote transit near the Lake County and Harney County line.
