Jackass Mountain and the adjacent Jackass Butte dominate this section of the High Desert, rising above the southeastern edge of the Harney Basin. The landscape is defined by its water management systems, notably the Buena Vista Canal which cuts through the Blitzen Valley to reach Buena Vista Lake. This network reflects the complex relationship between the arid terrain and the agricultural needs of the region in the early 21st century. High-clearance access routes like Jack Mountain Rd and the Jack Mountain Spur traverse the heights, while the Black Rim escarpment provides a sharp geographical boundary to the west. The presence of Or-205 along the eastern edge of the valley floor serves as the primary artery connecting these remote landforms.
