The story behind the photo: Union Falls is the second highest waterfall in Yellowstone National Park at 265 feet. However, you cannot drive to Union Falls, nor take a simple hike to Union Falls. It is lodged fairly deep inside backcountry. When you have a summer to spend in Yellowstone, however, these sorts of hikes are possible, and it is possible to do this hike as a day hike provided you don't mind driving over one of the worst roads in the country to get to the trailhead. One day off in 1998, I made a day hike out to Union Falls, and it was one of the most pleasant hikes I ever made in my life. After the lengthy down and up hike to the falls, I found myself in the midst of this amazing waterfalls, formed by the convergence of two rivers. Isn't that really cool? When I got there, a couple other hikers were taking in lunch at the falls, but by the time I took the shot I was the only person in the world looking at this waterfalls which appears like a head of angel's hair. There's nothing like seeing a wonder of the world all by oneself. Here's but a window into my day.
