Crystal Falls, MI is home to what may be the world’s largest and oldest living organism. It’s a fungus that lies beneath 38 acres of forest floor near the Wisconsin border. Scientists discovered the "humongous fungus" by accident in 1988. Experts believe it weighs around 100 tons and is between 1,500 and 10,000 years old.
But according to the Crystal Falls website, tourists who wish to see the giant fungus will probably be disappointed. It lives almost entirely underground, only sprouting a few edible mushrooms in the fall.
