On December 12, 2016 the National Park Service purchased 640 acres within Grand Teton National Park from the State of Wyoming. The Antelope Flats purchase was made possible by the successful completion of an eight-month fundraising campaign by Grand Teton National Park Foundation and the National Park Foundation that raised $23 million in private funds.
These funds were matched by $23 million from the federal Land and Water Conservation Fund. The newly protected land preserves critical wildlife habitat, migration routes, and viewsheds, prevents private development within the park boundary, and helps to complete the original vision of the park. The proceeds of the $46 million sale will benefit Wyoming public school children.
The Antelope Flats Parcel provides vital habitat for many species of wildlife.This tract of land lies in the path of a primary migration route for pronghorn, bison, and for the largest elk herd in the world. It is also adjacent to the most productive sage grouse lek in the region and provides important breeding, nesting, and brood-rearing habitat for many birds.
A former wolf den is near the parcel, and it contained the pack’s rendezvous site that was utilized by both pups and adults for an entire summer. Pronghorn are also common there, as are badger, coyotes, fox, and dozens of bird species.
The Antelope Flats Parcel has 360-degree, unobstructed views of the Jackson Hole valley.The Tetons’ Cathedral Group is to the west— which includes the Grand, Mount Owen, and Teewinot at the heart of the range, the iconic historic site known as Mormon Row and the prominent Blacktail Butte area are directly south, and the Gros Ventre Mountains are due east.
