Hey all, Tanguy Racine will be giving a talk on caves on Tuesday 8th December at 6 pm in Blackett (Department of Physics) Rm 630. Blurb: Where and how do caves form? How does geology influence cave formation? What even is geology? What even is a cave? We will address these questions during a presentation aimed at cavers, by a caver (and geologist). Concrete examples and fun quizzes throughout - bring an internet enabled device. Cheers, Jack -- Imperial College Caving Club <http://union.ic.ac.uk/rcc/caving>
