I have been to Coral Castle and it is very striking.. When I think about that I was alive while the people who did some of these things were also alive, that feels so frustrating, like why didn't I get there sooner..
No wonder I feel rushed.
Here are a couple of book recs for you too:
Harvey Lisle's "The Enlivened Rock Powders"
Julius Hensel's "Bread From Stones"
