It’s International Mountain Day! Not only are mountains majestic, they’re also critical to the water cycle, food production and tourism. If you asked someone to draw a mountain, they’d probably sketch something like the rugged beauty of Grand Teton National Park in Wyoming. With its snow-capped peaks catching the sunrise light above the Snake River, it’s one of the most stunning sights in America. Photo by Adam Jewell (www.sharetheexperience.org).
