Run on the trails at fairy stone state park before leaving for home. It was a beautiful sunny morning and we had the trails to ourselves. Legs are pretty beat.
We visited this park ~8 years ago to search for “fairy stones”. They are a unique mineral feature found only a few places in the world, where due the crystal structure and geothermal processes, the rock forms in a cross shape. We didn’t have time to search today, but I still geek out about it as a material scientist.
