The Woolaroc Museum & Wildlife Preserve gets its name from woods, lakes and rock, the three elements that dominate its landscapes. Established in 1925 as a private ranch retreat, the 3,700-acre preserve is today home to elk, buffalo and longhorn cattle, as well as a 50,000-square-foot museum dedicated to the history and heritage of the American West's first residents.

The two rugged granite rock mountain ranges of Wichita Mountains Wildlife Refuge once protected Native Americans from detection by the U.S. Calvary. Since the early 1900s, bison and other endangered species have found refuge within the walls and canyons that enclose its natural plains habitat. Roughly 650 American bison call it home, along with Rocky Mountain elk and white-tailed deer. The refuge also maintains a herd of Texas longhorn cattle to preserve the cultural and historical legacy of the breed.

Situated on the panhandle near the border with Colorado and New Mexico, Black Mesa State Park gets its name from a layer of lava rock covering the plateau. A trail leads to the top of the mesa – Oklahoma's highest point at 4,973 feet. Birders come to the park to spot pinyon jays, golden eagles, black-billed magpies and a host of other species.

One of Oklahoma's more unique natural attractions is Great Salt Plains State Park, a barren landscape leftover from prehistoric days when an ocean covered the state. The last remnant of this ocean is a saltwater lake where visitors can float, swim or fish. Recreational trails facilitate hiking and horseback riding, and unique hourglass-shaped crystals form just beneath the surface of the salt plains – a natural treasure hunt.

The outdoor memorial includes a 318-foot reflecting pool, Survivor Tree, Rescuers Orchard and the Field of Empty Chairs, each chair representing one of the 168 lives lost.
