2020 Map of Sandrock Mountain

About this map

Sandrock Mountain and Horse Heaven Mountain anchor this central Oregon landscape along the border of Jefferson and Wheeler counties. The terrain is defined by a dense network of geological landmarks and water sources, including the distinct formations at Balanced Rocks, Indian Rocks, and the interestingly named Hole in Wall Rock. This high-desert environment shows a clear dependence on natural springs for livestock or early settlement, evidenced by White Rock Spring, Oler Spring, and Broken Shovel Spring. Steep canyons such as Domogalla Canyon and Studhorse Canyon cut through the volcanic topography, while the presence of Log House Spring suggests a history of localized human habitation or range management. Navigational points like Tompkins Pass and Red Gap indicate the natural corridors used to traverse this complex system of gulches and hollows.
