The stillness of a winter sunrise is a moment to cherish at Rachel Carson National Wildlife Refuge in Maine. Established in 1966, the refuge protects salt marshes and estuaries important for migrating birds. Stretching from the coast to inland forests, the refuge offers amazing views and wildlife watching on five excellent trails. Photo by Ward Feurt, U.S. Fish and Wildlife Service.
