Great Rift volcanic formations dominate this portion of the Snake River Plain, where the landscape is defined by extensive Lava flows and geological fissures. The survey reveals a stark and complex terrain along the boundary of Blaine and Butte counties, characterized by numerous volcanic vents and depressions such as the Devils Caldron. Standing above the surrounding basaltic field are prominent features like Pratt Butte and Rattlesnake Butte, which served as critical landmarks for navigating this austere environment.
