On the Edge, an Exploration of Cattail Canyon

From it's beginning in the high Chisos Mountains of Texas' Big Bend National Park, Cattail Canyon remains one of the most rugged and remote locales in the lower 48 states. Over the years, John Sellers, led several expeditions into challenging and unexplored reaches of the canyon.
