Dunes Overlook Trail, Great Sand Dunes National Park, Colorado, USA
USA

Mount Herard of the Sangre de Christo mountains rises above an unusual sand dune field, part of the Great Sand Dunes National Park and Preserve. Competition between the prevailing winds from the west and opposing winds from the Sangre de Christos help keep the dunes in place.  Most of the sand originated as volcanic rock about 50 miles away in the once mighty San Juan volcanos, now worn away over millions of years to be trapped at the foot of the Sangre de Christos.

More About USA

The United States is one of the most diverse countries on earth, jam packed full of amazing sights from St. Patrick's cathedral in New York to Mount Hollywood California.The Northeast region is where it all started. Thirteen British colonies fought the American Revolution from here and won their independence in the first successful colonial rebellion in history. Take a look at these rolling hills carpeted with foliage along the Hudson river here, north of New York City.The American south is known for its polite people and slow pace of life. Probably they move slowly because it's so hot. Southerners tend not to trust people from "up north" because they talk too fast. Here's a cemetery in Georgia where you can find graves of soldiers from the Civil War.The West Coast is sort of like another country that exists to make the east coast jealous. California is full of nothing but grizzly old miners digging for gold, a few gangster rappers, and then actors. That is to say, the West Coast functions as the imagination of the US, like a weird little brother who teases everybody then gets famous for making freaky art.The central part of the country is flat farmland all the way over to the Rocky Mountains. Up in the northwest corner you can find creative people in places like Portland and Seattle, along with awesome snowboarding and good beer. Text by Steve Smith.
