We took a trip this weekend and went to a small family reunion in NC. Mom picked a park near one of my greats aunts and pretty centrally located to the rest of us, Morrow Mt State Park. The mountain range is located in the southern piedmont of NC. Part of the Uwharrie mountain chain, named for a local native tribe, Morrow is the highest peak at 936 feet. It and several other peaks are what remains of a chain that may be the oldest on the continent. They are the worn down remnants of an ancient group of volcanic islands. A chain of lakes occupies part of the valley floor now.
One thing that caught my eye was the stonework alongside the entrance road, the stone shelters and bathrooms. I asked the ranger about it. He said the stone came from the valleys and was metamorphic seabed, for years it has been marketed as Carolina Bluestone and thought of as slate, it is ardulite, I think a little harder than slate. We were picnicing at the peak, he proceeded to show us the igneous basalt and rhyolite that comprise the summit.
This is a bluestone chimney in a picnic shelter there. I liked the roof structure of the shelter, a queen post truss?
