Snowy mountains are gorgeous, but can be challenging models. Casey Withers was recently at Grand Teton National Park in Wyoming trying to capture the sunrise. It was a cold morning and clouds were moving in. “This shot was set up originally as a test shot as we waited for sunrise, but three minutes later the mountains were covered. Glad I was prepared.” Photo by Casey Withers. Posted on Tumblr by the US Department of the Interior, 12/22/15.
This is a different kind of traffic jam at Yellowstone National Park. Bison weigh up to 2,000 lbs and can pack a lot of attitude. They can run up to 35 miles per hour, but these appear to be taking their time. Photo by Allen Beyer. Posted on Tumblr by the US Department of the Interior, 12/27/15.
