Great Rift volcanic terrain dominates this high-desert landscape on the border of Blaine Co and Power Co. This 2017 survey details a stark geologic environment where prominent landmarks like Mosby Butte and Horse Butte rise above the surrounding lava fields. The presence of the Bear Trap Lava Tube in the southwestern quadrant underscores the area's complex subterranean structure. Human passage through this remote section of Idaho is primarily marked by the historic Minidoka to Arco Rd, which cuts across the northwestern corner of the quadrangle. The map serves as a precise record of township and range divisions, including t4s r28e, in a region defined more by its natural volcanic history than by dense settlement.
