Steens Mtn dominates the high-elevation landscape of this Harney County quadrangle, a region defined by dramatic glacial carving and deep drainage basins. The massive Kiger Gorge serves as a central geological landmark, while the unusual depression known as Hole in the Ground sits tucked near Trail Cr in the southeastern corner. This area remains largely defined by its natural hydrology, with numerous seasonal and perennial flows like Kiger Cr, Big Pasture Creek, and Cucamonga Cr dissecting the high desert plateaus. Modern access to this remote corner of the Oregon high country is primarily facilitated by the Diamond Loop Back Country Bywy, which skirts the western edges of the terrain near McCoy Ridge. The density of named creek systems, including W Fork Big Pasture Cr and Mud Cr, suggests a landscape shaped by significant snowmelt and runoff patterns.
