Write 5 sentences about the deposition in the Palo Duro Canyon

Palo Duro Canyon is a canyon system of the Caprock Escarpment located in the Texas Panhandle near the cities of Amarillo and Canyon. As the second-largest canyon in the United States, it is roughly 120 mi (190 km) long and has an average width of 6 mi (9.7 km), but reaches a width of 20 mi (32 km) at places. Its depth is around 820 ft (250 m), but in some locations, it increases to 1,000 ft (300 m). Palo Duro Canyon (from the Spanish meaning "hard wood" or, more exactly, "hard stick") has been named "The Grand Canyon of Texas" both for its size and for its 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.
