A waterfall on near Canorjie, NY with and a view of a shale outcropping. This and other rivers in the area used to flow west towards the Great Lakes Basin. At the end of the most recent ice age 16,000 years ago a huge meltwater lake, Lake Iriquois formed in the Great lakes area larger than Lake Ontario and Lake Erie combined. The east shore of this lake was a remnant lobe of ice that spanned the ancient Mohawk River Valley. This ice dam eventually melted and broke sending a huge torrent of water tearing through the valley to the Hudson River Basin. As the water camethrough it quickly eroded the softer shales that overlie a thick limestone sequence, stopping when it reached the more resistant limestone. Note the shale canyon wall exposed to the right of the falls and the flat limestone river bottom.
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.
