Palo Duro Canyonis a canyon system of the Caprock Escarpment in the Panhandle of Texas (USA). As the second largest canyon in the United States, it is roughly 193 km (120 mi) long and has an average width of 10 km (6.2 mi), but reaches a width of 32 km (20 mi) at places. Its depth is around 250 m (820 ft) but in some locations it can increase up to 304 m (997 ft). Palo Duro Canyon has been named "The Grand Canyon of Texas," both for its size and for the dramatic geological features, including the multicolored layers of rock and steep mesa walls similar to those in the Grand Canyon.
The canyon was formed by the Prairie Dog Town Fork Red River which initially winds along the level surface of the Llano Estacado of West Texas then suddenly and dramatically runs off the Caprock Escarpment. Water erosion over the millennia has shaped the canyon's geological formations. For More Visit Wikipedia
