About this map

Groan Canyon and its neighboring Mickey Canyon define this high-desert reach of Malheur County, where the management of water is the primary architectural footprint on the land. The landscape is punctuated by a network of engineered catchments, including Red Line Reservoir, Corner Reservoir, and the tandem Arrowhead Reservoir Number One and Arrowhead Reservoir Number Two. These features, alongside isolated watering points like Little Hole Spring and Mud Spring, reflect the vital infrastructure required for ranching in the Oregon backcountry.

Transportation is limited to a few primitive routes such as the North Fork Ryegrass Creek Rd, which winds through the western portion of the quadrangle. Drainages like Palomino Creek and Johnny Creek create a seasonal hydrologic rhythm, feeding into larger basins like Hub Reservoir and Antelope Pond. This 2011 survey documents a terrain where survival is tied to these dispersed water sources and the canyons that break the high-plateau relief.
