Big Bend National Park is a geological marvel evidenced in sea fossils and dinosaur bones to volcanic dikes that mar the desert landscape. It's a world of species diversity from the meandering river corridor that sidles across the desert floor to the sky island ridge tops that reach for the stars. It's a place where you can still hear the whispers of pioneers, ranchers, miners, and Native Americans. And it's a land of borders—a place where countries and cultures meet.
