About this map

Turpin Knoll stands as a central topographic landmark in this high desert region of Harney County, where the landscape is defined by its careful management of water. The distribution of small catchments like Clay Reservoir, Shale Reservoir, and Quarter Corner Reservoir reveals a land utilized for seasonal grazing, where every draw and canyon is critical for resource management. The terrain shifts from the prominent Rehart Rim in the west toward the broad expanse of Dry Valley to the east, illustrating the complex drainage patterns of the Great Basin.

Water sources are often named for the early inhabitants and seasonal users of the range, such as the McCarty Cabin Waterhole. Other features like Packsaddle Draw and Turpin Canyon suggest a history of traverse and livestock movement through these draws. Near the center of the southern range, the seasonal Large Lake and the winding course of Juniper Cr highlight the hydrology that sustains life in this arid Oregon interior.
