There are no Antelope on Antelope Island, in The Great Salt Lake, Utah. In fact, there are no antelope in North America, just like there are no buffalo, they are only found in Africa.
They are pronghorn.
The first white man to see the Great Salt Lake was Jim Bridger in 1824 while on a trapping expedition. In 1843, explorer John C. Fremont, with his guide, Kit Carson, led an expedition to map the Great Salt Lake. Pronghorn, which Fremont called antelope, roamed the island, and therefore Fremont named the island Antelope.
Boy, was the song: “Oh, give me a home where the Buffalo roam Where the Deer and the Antelope play;” really got it wrong.
Nevertheless, there are also Bison on Antelope Island.
We both hiked and drove around the Island.
The Mormons used the Island to graze cattle in 1848, with Fielding Garr building a ranch on the Island that was used until 1981.
Both the Bison (I guess they should call Buffalo Bill Cody, Bison Bill Cody) and Pronghorn roam free on the 43 square mile Island, the largest of 10 island in the The Great Salt Lake.
Barbara found the bison fur to be very soft.
(That Bison was not happy when she tackled him to the ground to get that sample.)
