Yesterday I went hiking in an abandoned coal mine here in central Pennsylvania. Found two excellent examples of prehistoric Earth’s K-T Boundary. https://en.wikipedia.org/wiki/Cretaceous%E2%80%93Paleogene_boundary Shocked quartz crystallized and sandwiched between layers of molten granite when the dinosaurs died. 🦖🦕🌋💎⚒ ...good hobby 💰 but I think I’ll keep the right angled one for a cool bookend 😉
Today I’m going back hunting for bigger quartz crystals Saw many reflected in my torch lamp, but it was getting dark and cold so I had to leave them for the time being. Stay tuned...
