Ownership changed hands several times before being acquired by Utah State Parks and Recreation. Two thousand acres were purchased in 1969, and the balance in 1981.
Antelope Island’s 28,000 acres makes it the largest of the ten islands in the Great Salt Lake.
As a small remnant of prehistoric Lake Bonneville, it once covered 20,000 square miles of land in what is now Utah, Nevada, and Idaho.
Elevation ranges from 4,200 feet at lake level, to 6,500 feet on Frary Peak. Access to the island is via a seven mile causeway.
Geologic features include several levels of historic Lake Bonneville as well as remnants of ancient volcanoes.
The island’s population of big game animals includes Mule Deer, Antelope, and Bighorn Sheep and is highlighted by a herd of American Bison.
The free roaming American Bison herd numbers range from 500 to 700 depending on the time of year.
Other animals that call the island home are Coyotes and numerous species of small mammals and birds.
