THE CONCRETION
Washington Park, downtown Sandusky
This plaque is located on a large spherical concretion, discovered in 1910. This unusual geological formation is located in downtown Sandusky in Washington Park between Columbus Ave. and Wayne St., near the Gazebo. This concretion was formed in sedimentary deposits over the ages. An unusually large specimen, it was found in 1911 on Mills Street and brought to this site at the behest of Prof. E. L. Moseley, who was noted for his studies of Lake Erie and his natural history museum. It was on a pedestal in this park for about eighty years. In 1990 it was partially buried to halt deterioration.
