Aftermath of a forest fire in Yellowstone National Park, Wyoming

This summer, to celebrate the first 100 years of the National Park Service, each Friday is National Park Day on Bing’s homepage. Every week we’ll be visiting a different US national park. It’s a road trip! And we’re kicking it off in the park where it all began—Yellowstone, pictured here in the aftermath of a forest fire. Yellowstone was the world’s first national park and the foundation for what became ‘America’s best idea,’ the US national parks.

While we’re here in Yellowstone, what are the things we can’t miss? Been there before? Share some of your best photos on Facebook, Twitter, and Instagram, where you can also follow our progress and help us along the way. Stay in touch—we’ll be visiting the mysterious Black Canyon of the Gunnison next.
