National Parks Traveler: Understanding Big Bend National Park

The National Parks Traveler’s Lynn Riddick begins a two-part series about her recent trip to Big Bend -- a vast wilderness in the Chihuahuan Desert along the Rio Grande. She meets up with the park’s chief of interpretation, who offers an overview of the park’s varied geology and diverse ecology, its human history and what the future may hold for visitors seeking adventure and solitude in the park’s 800,000 acres.
