PLEASE HELP!!!!!!!

Palo Duro

Some places simply warrant more attention. One of the most illustrious sites in the world is known by very few except regular adventure-goers. Travelers are awed by Palo Duro Canyon as its deep, red landscape appears seemingly out of nowhere. The canyon, similar in length to the Grand Canyon in Arizona, has scenic views just as glorious as those of the more famous canyon. At night, coyotes can be heard in the distance as the high winds gust through the valley, echoing the howls off the steep canyon walls. During the day, the hateful sun heats up every visible crevice, providing a contrast to the cool, breezy nights. The favorable aspect of the day is its gift of sight, of the stunning erosion that has taken place over millions of years, or of the rocks impossibly balanced on one another and their relentless determination to remain unmoved. This place and its striking diversity deserve recognition for doing exactly what nature does best: providing wonder to all.
