Flint Ridge Ancient Quarries and Nature Preserve

Flint Ridge Memorial is a small preserve on an extensive vein of Vanport Flint in central Ohio.  The beautifully colored flint was valued for making tools and ceremonial objects by the indigenous people of this area and beyond for thousands of years.  Tools made from this distinctive material have been found as far away as the Rocky Mountains and Gulf coast.   The Memorial preserves ancient quarry pits and natural outcrops of the rock. Vanport flint has been declared Ohio’s official gemstone.

  1. Thanks for these, Mic. I’ve wanted to visit Flint Ridge, but haven’t been there when open.

    Have a great Christmas to the Miller clan.

    1. We drove down for a quick day trip. The museum is closed until next spring but it was interesting to walk the trails and visit it again. I like the area with the mounds in Newark and Granville area and the Blackhand Gorge is interesting on both sides of the river.

      Best wishes for the holidays, Dave. Nice to hear from you.

  2. Interesting, Mic. Rocks fascinate me, and this flint is beautiful. I appreciate the way you have a detailed image showing the colors and sharp edges as well as the context image, where I can imagine the rock lurking under those leaves. I would be happy to see more! 🙂

    1. Thanks, Lynn. The flint is in a vein 2 to 10 feet thick covering an area about 3 miles by 9 miles and about 8 to feet below the surface. It modifies the ecosystem by limiting how large trees can grow before they fall over and by giving rise to many vernal pools.

      1. And maybe it changes the plant life a bit in other ways, too – sometimes, different rocks have their attendant plant communities, as I’m sure you know. These odd habitats are so interesting – and vernal pools – they’re always intriguing too.

      2. Isn’t it wonderful? The natural world is so complex and varied that no matter where you look it provides a never ending supply of unanswered questions, surprising little discoveries, and ideas to think about, not to mention beautiful vistas and tiny little details to photograph 🙂. Summed up very well in Mary Oliver’s poem “Mysteries, Yes” if you like her poetry.

        Best wishes for the holidays, Lynn.
