Maybe you are into tumbled stones, crystal healing, and moonstone jewelry, and maybe that's as far as it goes. But what ARE the rocks and crystals we work with? What makes them special? There's more to the earth than just the plants that grow out of it--the deep time of the planet and the process that formed it and everything around us (That are still forming it!) can affect our Craft in incredible ways. At least, that's what Betwixt and Between think (and Between is really into it right now, because she's doing geology with her daughter in homeschool).   For more, and more accurate, information, visit the GODDESS of Witching Geologically, Kathleen Borealis:   http://katborealis.com/   This Youtube video is a great overview of the formation of our planet:   https://youtu.be/uHUTbq-j0UU   And you know you want to learn about crinoids!
