Sauta Cave National Wildlife Refuge (formerly known as Blowing Wind Cave NWR) lies just above the Sauty Creek embayment of TVA's Guntersville Reservoir, 7 miles west of Scottsboro, Alabama. The refuge consists of upland hardwoods and limestone rock out crops. The cave has a double entrance, upper and lower, and is critical habitat for endangered gray and Indiana bats. The cave serves as a minor hibernation area for Indian bats and historically as a major maternity cave for gray bats.
