On Saturday, March 24, 2012, Col. Matthew W. Nahorn participated in the annual Vermilion River Watershed Open House at the Vermilion-on-the-Lake Clubhouse along Lake Erie in Vermilion, OH. He represented the Beaver Creek Watershed Protection Group as Watershed Coordinator. A display highlighting and explaining the Beaver Creek Watershed was accompanied by a display of early prehistoric tools from the region. These tools, from the collection of the New Indian Ridge Museum, were presented to demonstrate tools that were used by early prehistoric inhabitants of Northern Ohio. The open house was well-attended, and many interesting conversations took place.
