Saturday was a busy day on Antelope Island in Utah, about 200 cowboys and cowgirls saddled up and herded the island's bison. The bison were herded into corrals on the north end of the island, as part of the annual round-up. The bison will be inspected by veterinarians to determine herd health and will receive vaccinations.
In mid November about 200 bison will be auctioned off. This helps keep the herd at a sustainable level on the island and the money goes to support wildlife programs.
There have been bison in the island since 1893, when a boat took a dozen over to the island. From The Salt Lake Tribune .
