Rocks/Gemstones

Ohio’s gemstone, flint, is a unique rock with many different shades of red, gray, blue, white, pink, black, and green.  As a variety of quartz, it is composed mainly of silica; the colors are impurities that intermingle with the silica, giving flint many striking appearances, such as iron (rust) giving the red hues.

If you have large sandstone foundation stones in your home or sandstone sidewalks, chances are they came from Lowe-Volk Park. Visit the nature center to see & read about our quarry. Hike the trail along the Sandusky River to see this sandstone in its natural form.
