2020 Map of Whitehorse Butte

About this map

Owyhee River flows through the deep southwest corner of this high-desert landscape in Malheur County, carving the Owyhee Canyon near the historic Deary Pasture. The 2020 map documents an intricate network of livestock water management features across a landscape dominated by basalt ridges and ephemeral drainage basins. Named reservoirs like Seldom Reservoir, Slipper Reservoir, and Deary Reservoir highlight the necessity of water storage in this arid environment. Significant topographic features such as Horse Ridge and the prominent Whitehorse Butte define the horizon, while drainage is handled by systems like Mud Flat Creek and Soldier Cr. The presence of Arritola Place Rd and Three Forks Rd provides the primary access through this remote cattle country, connecting scattered points like Groundhog Falls and the Rim Basin.
