Hope it goes well Tony; I’m giving a talk about Siccar Point next week to my u3a group, so I too am revising ☹️ #unconformities quite enjoying it 👍👍 🪨

It went well, thanks, Peter! Unconformities are among my favorite geological concepts to teach for their intersections of reality (the rocks are there) and high concept (so much time and time lost also there). And of course Siccar Point is a great example for its relation to history of science. ⚒️🧪🪨
