Sacred Waters: The Okefenokee in Peril: Sacred Waters, presented by OPA with the generous support of the National Parks Conservation Association, takes viewers into the heart of the Okefenokee National Wildlife Refuge, showcasing its mystical natural beauty, cultural importance, and incredible ecological value. The threat of a proposed heavy mineral sands mine near the edge of the Okefenokee looms large, putting the natural integrity of the Swamp at risk. As Sacred Waters brings us deeper into the Okefenokee, we understand how great this threat truly is.
