On this day 145 years ago, the world’s first national park, Yellowstone National Park, was created. For anyone who has visited this incredible land of fire and ice and marveled at the amazing wildlife and unique geologic features, there’s little doubt why Yellowstone is considered one of our nation’s greatest treasures. Even if you weren’t one of its more than 4 million visitors last year, you can still discover fun facts about the park: http://on.doi.gov/24zbV9d Photo courtesy of Michael Hardridge.

Just outside of Washington, D.C., in Virginia, Great Falls Park is the perfect place to get some exercise. There’s hiking, biking, fishing, climbing and boating opportunities.

This week, Grand Canyon National Park celebrates its 98th birthday. Long before it became a national park, this landmark’s timeless beauty was well known throughout the country and parts of the world. Today the canyon is no less a source of inspiration than it was for these early tourists.
