Mystery Hill Marblehead, Ohio is well known for its limestone quarry. Millions of tons of stones are shipped throughout the great lakes from this quarry every year, but one section of this quarry was never excavated and quickly sold after workers complained of strange and abnormal events. In 1953 a house was built on this plot of land. This house with the strange effect of gravity still exists as Mystery Hill. You can still visit this spot and experience first hand the unusual forces. Water runs uphill! Will you be able to explain these forces??? Or will you just enjoy the fun you can have with friends & family at this unique location.
