The magnificent sky reflects a blend of colors on the water at Blackwater National Wildlife Refuge in Maryland. A patient, great blue heron fishes as the sun sets, reminding us that the crepuscular hour is an excellent time to watch for wildlife. With four land trails and over 20,000 acres open for public recreation, the refuge has activities for visitors all year long. Paddling, hiking, fishing or spotting bald eagle nests are just a few reasons people return to this compelling place time and time again. Photo by Zolt Levay (www.sharetheexperience.org).
