Clyde Butcher believes South Florida's wetlands have an image problem. Everglades National Park and the adjacent Big Cypress National Preserve are unique, awe-inspiring places. But they're also swamps, with alligators, snakes and high water that discourage visitors from experiencing much of the beauty. For nearly three decades, Butcher has captured much of that beauty in his large-format, black-and-white photographs. They've won him acclaim as an artist and as an educator who's worked to spread the word about an area that's been called Florida's "last frontier."
