About this map

Groan Canyon and the surrounding high desert of Malheur County are defined by a network of seasonal water catchments and isolated springs essential for land management. This 2023 survey illustrates a landscape of complex topography, where the Palomino Hills and Sheepshead Mountains overlook deeply incised drainages like Bone Canyon and Mickey Canyon. The distribution of water is a central theme, documented through numerous named reservoirs including Arrowhead Reservoir Number One, Arrowhead Reservoir Number Two, and Hub Reservoir.

Access to this remote region is limited to primitive routes such as the N Fork Ryegrass Creek Rd and Three Forks Reservoir Rd. Historically significant water sources, often vital for local ranching and wildlife, are scattered throughout the terrain, including Antelope Spring, Whitby Spring, and Early Spring. This map provides a detailed view of the modern infrastructure and natural hydrology in one of Oregon's most secluded corners.
