Muscatatuck National Wildlife Refuge – the first wildlife refuge in Indiana created 50 years ago this week – protects habitat for more than 280 species of birds like sandhill cranes. The refuge was also instrumental to the comeback of the state’s endangered North American river otter, serving as the first release site to bring populations back to healthy numbers. This amazing landscape of lakes, marshes and creeks is a quick trip from major metropolitan areas in Indiana, Ohio and Kentucky. Photo by Susan Harner, USFWS.
