RE: A Messenger From Heaven or a Visitor from Hell?

Thank you, @agmoore! It was fascinating following the trail crumbs that would lead me to an answer. The geology around these parts has experienced some tectonic upheavals, so it's a great place to study those processes. The planet as a whole has gone through many changes across millions of years, so the secrets are partly buried in those rocks and stones. It's a mysterious chapter in the history of earth and planet formation in general.
