About this map

Mann Lake Ranch anchors the northwestern corner of this high-desert landscape in Harney County, illustrating the sparse but vital human footprint in this part of Oregon during the early 1980s. The terrain is dominated by the expansive Miranda Flat and the deep Depression to the south, highlighting a topography shaped by interior drainage and seasonal water flow. A network of ephemeral streams, including Castle Rock Creek, Little McCoy Creek, and Mosquito Creek, descends from the eastern heights toward the flatlands.

Evidence of remote infrastructure is visible in the presence of a Landing Field and several water-management features like a Flowing Well and Water Tank. These elements, along with various corals and 4wd tracks, point to the cattle ranching and land use patterns typical of the Great Basin. The map also records localized industrial activity at a Borrow Pit near the center of the quadrangle, serving as a specific waypoint for local history researchers and land management studies.
