Irish Hills Michigan is nowadays mostly known for its lush forests, plentiful outdoor activities, and an abundance of Irish Americans, however, in the 60's, it had a booming tourism industry with many colorful and exciting attractions that drew in visitors from all over Michigan. One of these attractions was Prehistoric Forest, a theme park mostly known for its dozens of dinosaur statues made of fiberglass and styrofoam. When the park closed in 1999, the statues were all left to rot where they stood, but this would ultimately lead to Prehistoric Forest's second life as a dream location for urban explorers.
