The ice caves at Apostle Islands National Lakeshore in Wisconsin. Accessible by foot when Lake Superior freezes over – which doesn’t happen every year – the caves are like a palace decorated with hanging blue ice formations. Photo by Wan Shi.

A trip to Yellowstone National Park in Wyoming isn’t complete without viewing the majestic Lower Falls. When visiting the park in 2012, Stuart Burnett and his wife Patti captured this shot of Lower Falls legendary rainbow thanks to detailed research and planning. Of the experience, Stuart says, “You could hear the gasp from the other viewers as the rainbow formed. It was just magnificent!! It lasted for about 10 minutes … 10 minutes that I will never forget!!” Photo courtesy of Stuart Burnett. Posted on Tumblr by the US Department of the Interior, 7/3/16.

Acadia National Park in Maine is known for its sunrises. The park is one of the first places to see the sunrise in the U.S., but its sunsets are also stunning! Photographer James Kaiser captured this magical view from the top of Cadillac Mountain after a rainy day: “Even when things seem gloomy, conditions can quickly change. It’s one of nature’s most important lessons, and national parks help us appreciate it firsthand.” Photo courtesy of James Kaiser. Posted on Tumblr by the US Department of the Interior, 8/2/16.
