Antelope Island, approximately ten miles long and four miles wide, is the largest island in Great Salt Lake. The island, which becomes a peninsula when lake levels are low, has easily accessible outcrops of some of the oldest (Precambrian-aged) rocks in Utah. It is also home to a variety of wildlife including pronghorn, bison, bighorn sheep, and millions of waterfowl.
