Michigan's largest freshwater spring pumps more than 10,000 gallons of water every minute, yet one of its most incredible features is something you can only fully appreciate by looking straight down.
Kitch-iti-Kipi, also known as the Big Spring, sits inside Palms Book State Park near Manistique in the Upper Peninsula. It's approximately 200 feet across, 40 feet deep, and filled with water so clear you can see ancient tree trunks resting on the sandy bottom.
The name comes from the Ojibwe language, with interpretations including "big cold water" and "mirror of heaven." Once you see that brilliant blue-green water, the second description makes perfect sense.
And here's what makes this place especially remarkable: The water stays around 45 degrees Fahrenheit all year long.
Even during a brutal UP winter, when snow blankets the surrounding forest and frost coats the trees, the spring remains open and unfrozen.
Visitors can experience this natural wonder aboard a self-operated observation raft. Using a hand crank and cable, you slowly pull yourself across the spring while looking through a viewing area in the center.
Below you, trout glide through the water, ancient logs rest on the bottom, and sand swirls where underground water rises through fissures.
It's like looking through a window into another world.
The spring is accessible year-round, with a short, accessible walk from the parking area. A Michigan Recreation Passport is required for park entry, and the observation raft accommodates wheelchairs.
Michigan has plenty of places that look beautiful in photographs, but Kitch-iti-Kipi is one of those rare places where the real thing is even more remarkable.
Only in the Upper Peninsula can a 40-foot-deep pool of freezing-cold water feel like a glimpse into another world.
