2010 Map of Bear Trap Cave

About this map

The volcanic landscape of southern Idaho is clearly defined by the primitive road network and subterranean geography of Blaine County. Centered on a remote landing strip, Bear Trap Airport serves as a lone navigation point among the sparse high-desert infrastructure. The road names themselves reveal the geological character of the region, specifically Bear Trap Lava Tube Rd, which traces the subterranean volcanic pathways common in this part of the Snake River Plain. Water management is critical in this arid environment, evidenced by the presence of Lulu Reservoir to the west. The terrain is punctuated by significant volcanic landmarks, most notably Split Butte, providing clear topographical orientation in a region defined by ancient lava flows and modern ranching or transit routes like the Minidoka to Arco Rd.
