Since 1981, the 28,000 acres that make up Antelope Island, complete with 6,300-foot mountain peaks, rolling pastures, white sand beaches and an abundance of wildlife, has remained a Utah State Park. It all began a few thousand centuries ago. The thinning and stretching of the Earth's crust due to plate movement created something known today as the Great Basin in Utah and Nevada. It is nothing more than the backwash of an ancient ocean called Lake Bonneville, which used to cover most of Utah, along with parts of Nevada and Idaho. The old shoreline of Lake Bonneville is still visible halfway up the slopes of Frary Peak on Antelope Island.
Seagulls are everywhere on the island.
Mother Nature has them fooled. They actually think they're at the ocean, but it's just a huge dead lake and lots of salty air. Three to nine times saltier than the ocean, this is not a lake to play in. And, yes, you do float, just like your sixth-grade science teacher told you. Someone bought 12 of those bison from a ranch in Texas and placed them on Antelope Island.
