Pics: America's first national park
The national park system offers access to boundless beauty, break-taking views and a great way to "tune out" and simply get back to nature. This series of slideshows will take a look at these parks. We hope that you will someday be encouraged to travel to one of these parks and see the wonders for yourselves. Today we start with the first national park, Yellowstone. Sitting on one of the largest volcano calderas on the planet, Yellowstone is a wondrous and beautiful journey. Enjoy!
