2017 Map of Bear Trap Cave

About this map

The volcanic geology of Idaho's Snake River Plain dominates this modern survey, defined by the extensive Wapi Flow and the northern reaches of the Craters of the Moon National Monument. The landscape is a study in subterranean and surface lava features, prominently featuring the Bear Trap Cave and the Bear Trap Lava Tube in the northern sections. Human presence is sparse and utilitarian in this arid environment, represented by the remote Bear Trap Airport and the lonely course of the Minidoka to Arco Rd. While the terrain appears desolate, the inclusion of Lulu Reservoir and markers like Split Butte indicate the careful mapping of vital landmarks and water resources necessary for navigating this complex volcanic field.
