In this episode, I interview Bob Krumenaker, retired Big Bend National Park superintendent, about the recently proposed Big Bend border wall and its implications. Bob describes Big Bend’s desert, Chisos Mountains, and the Rio Grande riparian corridor, emphasizing biodiversity, cross-border wildlife movement, and the park’s international protected-area status. He argues Big Bend has the lowest illegal crossing activity on the southern border—about 200 apprehensions annually within the park—and says a 30-foot bollard wall would require new roads, towers, lighting, and secondary barriers, harming wilderness character, dark skies, river access, and wildlife. The discussion covers existing surveillance infrastructure, an MOU guiding Border Patrol conduct, prior wall impacts in Organ Pipe and Coronado, and a nonpartisan coalition opposing the wall while supporting less intrusive, cooperative technology. Bob also outlines advocacy steps and links the fight to long-stalled wilderness designation efforts.
