DETAILS:

Established in 1901, Wichita Mountains Wildlife Refuge is one of more than 546 refuges throughout the United States managed by the Fish and Wildlife Service. The 59,020 acre Refuge hosts a rare piece of the past - a remnant mixed grass prairie, an island where the natural grasslands escaped destruction because the rocks underfoot defeated the plow.
