Redstone Trail, Lake Mead National Recreation Area, Nevada, USA
Nevada

The red rock of southern Nevada, known as Aztec sandstone, was born of the same sand dunes that gave birth to the red rock exposed in the Colorado Plateau further east.  Those dunes spread in a vast desert during the age of the dinosaurs and covered much of what is now Utah, southern Idaho, eastern Nevada, Arizona and New Mexico.

The Aztec sandstone is visible throughout much of the Lake Mead National Recreation Area as well as the Valley Of Fire state park to the north and the Red Rock National Conservation Area north of Las Vegas.  In all three areas, much older 500 million year old limestone rises in peaks above the red rock.  Thrust faulting has lifted the older rock above the younger.

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.
