2024 Map of Whitehorse Butte

About this map

Whitehorse Butte anchors this landscape in Malheur County, where the high desert is defined by a complex network of ranching infrastructure and seasonal water sources. The Owyhee Wild and Scenic River carves through the southwestern corner, forming the deep Owyhee Canyon near Deary Pasture. This modern survey reveals how water management shapes the area, with numerous impoundments such as Jaca Reservoir, North Whitehorse Reservoir, and the West Whitehorse Reservoir providing critical storage. High points like Horse Ridge and depressions like Rim Basin break the plateau, while Groundhog Falls marks a rare vertical break on Mud Flat Creek. The presence of roads like Arritola Place Rd and Three Forks Rd suggests the continuing utility of these routes for land management and recreation.
