The rocky terrain of Wichita Mountains National Wildlife Refuge in Oklahoma is an oasis of natural grassland among developed farms. Almost 60,000 acres are now home to reintroduced species including bison, elk, prairie dogs, river otters and burrowing owls. Visitors can enjoy wildlife watching, fishing, climbing, hunting and walking among wildflower blooms. Photo by Daniel Suh (http://ift.tt/18oFfjl).
