 Squire Boone died of congestive heart failure, at age 70, on August 5, 1815 and was buried in a cave on his property.His remains were left undisturbed for many years, but in the mid-20th century relic hunters began taking parts of his coffin and even some of his bones.In 1973, his remains were removed from a small pit cave on the property and placed into a new coffin built by employees of the cave and placed inside the commercial cave, where it resides today, at the end of the tour of Squire Boone Caverns.
