Skull Cave boasts a rich and captivating history, beginning with its geological formation. It was carved by the powerful wave action of Lake Algonquin, a glacial ancestor of Lake Huron, during the post-glacial period, approximately 11,000 years ago. This process eroded softer rock around a durable 30-foot-high limestone stack, leaving behind the cave. The cave holds profound significance for Native American tribes, particularly the Anishnaabek (Odawa, Ojibway, and Potawatomi), who used it as an inhumation or burial site for centuries, well into the 18th century. Its ominous name originates from the human bones and skulls discovered there by early European explorers. The cave's mystique was further amplified in 1763 when English fur trader Alexander Henry sought shelter within its confines during Pontiac's War. He famously recounted waking to find himself lying amidst a heap of human remains, an event that became a pivotal part of the cave's legend. Skull Cave was designated a Michigan Historic Site on January 12, 1959. Today, the cave is protected, with access restricted by a fence, and interpretive signage educates visitors about its storied past.
