Palms Book State Park

Palms Book State Park is a publicly owned nature preserve encompassing 388 acres in the eastern Upper Peninsula of Michigan. The state park is noted for Kitch-iti-kipi, the "Big Spring" of the Upper Peninsula. Michigan's largest freshwater spring, spanning 200 feet across and 40 feet deep, can be seen from above as it wells upward through the pond's bottom of bedrock limestone and sand, creating a continual pattern of random eddies and cross-currents in the depths of the pond. To the Anishinaabe people who were the original inhabitants of much of the Upper Peninsula, this site was a place of mystery and wonder. The flow continues throughout the year at a constant 45 degrees Fahrenheit, gushing more than 10,000 gallons of water a minute from fissures in the underlying limestone.
