The high-elevation divide between the Malheur National Forest and Whitman National Forest defines this landscape in the southern Blue Mountains. Straddling the Grant and Baker county line, the area is dominated by complex water management and seasonal access routes. The S Fork Burnt River and its tributaries, such as Sheep Cr and Elk Cr, are fed by numerous named springs including Mammoth Spring and Tamarack Spring. Human engineering for water transport is evident in the presence of Cavin Ditch and Elms Ditch, which redirect flow across the high plateaus. The modern recreational character of the land is visible through an extensive network of off-highway vehicle and snowmobile trails, such as the Blue Mtn Ohv-1 and Pole Creek Snowmobile, which provide passage through landmarks like Buck Mtn and Mine Ridge.
