Think you know your sedimentary from your metamorphic? If so, York Geology Club are looking for rock enthusiasts like you. During the winter, the club meet on every second Wednesday of the month at the Friends Meeting Room off Castlegate. For those outdoorsy types, folks at the club also organise field trips to local and not-so-local places in the summer, giving geology fans the chance to see how rocks inter-relate with the landscape and even start their own collection of fossils. You don't need to be a Nobel Prize-winning geologist to join, so long as you're happy to join in a bit of friendly banter.
