Hart Mountain National Antelope Refuge dominates the eastern high desert landscape, where the dramatic elevation changes of Poker Jim Ridge transition into the expansive flats of the Warner Valley. This 2024 survey documents a critical intersection of hydrology and topography, capturing the seasonal character of Bluejoint Lake and the drainage patterns of Rock Creek as they navigate the rimrocks. The rugged verticality of the escarpment is punctuated by Snyder Canyon, providing a detailed view of the natural corridors that define this protected habitat. In the far southeastern corner, Frenchglen Rd serves as the primary artery through this isolated terrain, crossing the boundary between Lake and Harney Counties.
