The shape of the southwestern edge of Texas is carved by The Rio Grande river, as it tranquilly flows bringing life to some of the most remote regions of the country. Here, the Rio takes a giant turn north, a Big Bend creating the heel in Texas's shape.

On this episode of America's National Parks, Victor Valdez, the singing man of Boquillas, and Big Bend National Park.
