The picture was taken from the floor of Palo Duro Canyon, the second-largest canyon in the U.S., located in the Texas Panhandle. Unlike Grand Canyon where most enjoy it from the rim and the adventurous visit the canyon floor, at Palo Duro camping and sightseeing are done on the floor of the canyon. It makes for a unique experience.
Here you are looking up from about 800 feet below the rim. The rock tower you see in the middle of the photo is called a hoodoo. Hoodoos and caves are seen throughout the canyon. The 120 mile long canyon Palo Duro Canyon was cut by the Prairie Dog Town Fork tributary of the Red River about a million years ago.
