Jay has a fascinating interview with Tom VandenBerg, Chief Ranger for the Interpretation and Visitor Services Division at Big Bend National Park in Texas. Tom holds a degree in Biology from U.C. Santa Barbara and has been a Ranger with the National Park Service serving in several National Parks including Yosemite, Everglades, Glacier Bay and Wrangell-St. Elias. His work at Big Bend includes evening programs, talks, guided walks, demonstrations and special events – and managing and staffing five visitor centers. In this interview, he talks about the geology, archeological sites, landscape diversity and wildlife at Big Bend – as well as rafting the Rio Grande along the Park’s southern border.
