About this map

Aa-Tiipi Flat and Tuu-Tiipi Flat define this high desert corner of Malheur County, where the landscape is marked by a sophisticated network of water management features. At this time, dozens of small catchments like Rock Reservoir, Mouse Trap Reservoir, and Yellow Fingers Reservoir dot the terrain, essential for supporting livestock in an arid environment. The land is punctuated by distinct volcanic and erosional forms, including Grassy Mtn and Mouse Trap Butte, which provide topographical relief against the sweeping flats. Access to these remote reaches is maintained by a handful of established routes, notably Skull Creek Rd and Upper Horse Camp Reservoir Rd, which skirt the edges of drainage systems like Loveland Canyon. The mapping reveals a pattern of modern rangeland utility, with each reservoir and butte serving as a vital landmark for navigation and resource location.
