2014 Map of Little Grassy Mountain

About this map

Little Grassy Mountain and Black Butte anchor this high-desert landscape in Malheur County, Oregon. The terrain is defined by a sophisticated network of water management, evidenced by numerous catchments including Little Grassy Reservoir, Greeley Reservoir, and Noon Reservoir. These features, along with the expansive Rock Creek Flat and Antelope Flat, suggest a region heavily utilized for seasonal rangeland. Access across the plateau is provided by remote routes such as Three Forks Rd and Arritola Place Rd, which connect various reservoirs and springs. The map also reveals interesting geological features like Hole in Ground and the dramatic drop into Owyhee Canyon at the southwestern edge, illustrating the transition from flat volcanic plateaus to deep river drainages.
