We can’t help but smile after seeing this big grin from one of the fishes at Florida Keys National Wildlife Refuge Complex. Comprised of four refuges situated in the Florida Keys, the complex protects the critical habitats on the land and in the water for wildlife like the American crocodile, the endangered Key deer, the Great White Herons and others.

Comprised of 4 million acres in southwest Alaska, Lake Clark National Park and Preserve is one of the nation’s most remote national parks. Winter conditions add more challenges to those wanting to explore this gorgeous and diverse landscape, but as you can see, the backcountry scenes are worth the cold.

As we celebrate Martin Luther King, Jr. Day, we remember his message of unity and service. One of the most influential people in our history, Dr. King’s legacy continues to inspire. At the Martin Luther King, Jr. Memorial on the National Mall in Washington, D.C., 14 quotes focusing on justice, democracy, hope and love surround the statue of him. Located a short walk from the Lincoln Memorial, where Dr. King gave his famous “I Have A Dream” speech, it’s a powerful and enlightening place. Photo by Jim Evangelista (http://ift.tt/18oFfjl).
