Just a short drive from Amarillo, Texas is the second largest canyon in America, located in Palo Duro Canyon State Park. The park—part of the 120-mile long canyon—offers scenic views, both by car and on foot, and also allows visitors a chance to travel back in time to see the remnants of how President Roosevelt’s Civilian Corps shaped the landscape.
