Huron National Wildlife Refuge is made up of eight small islands three miles off the Michigan shoreline of Lake Superior. Accessible only by boat, the refuge’s forests and bog provide habitat for birds like the herring gull, cedar waxwing and bald eagle. Visitors can stroll along Huron’s lone trail and take pictures of the historic stone lighthouse, the grays and pinks of the exposed bedrock, the blues of the lake and the contrasting greens of the trees. The bedrock itself offers shutterbugs a chance to capture the unique patterns caused by boulders cutting grooves into the rock as glaciers moved slowly over the landscape 8,000 years ago.
