The Antelope Island bison herd is in Antelope Island State Park in Great Salt Lake, Utah. The semi–free-ranging population of American bison (Bison bison, buffalo) has been in existence on Antelope Island since 1893. The island was named for the pronghorn antelope that John C. Frémont and Kit Carson found there when they explored the Great Salt Lake. Bison were later introduced. The herd is significant because it is one of the largest and oldest publicly owned bison herds in the nation. It is one of the two bison herds managed by the State of Utah, the other being the Henry Mountains bison herd. The Antelope Island bison herd currently numbers between 550 and 700 individuals. Other large free-ranging, publicly controlled herds of bison in the United States include the Yellowstone Park biso
