Stuff I linked to on Twitter last week

A post by Chris RowanBefore you check out the interesting bits of my Twitter stream for the last week, I highly recommend clicking through to the latest edition of the geology blogging carnival The Accretionary Wedge, hosted at Callan Bentley’s Mountain Beltway. The theme this month was ‘geological heroes’, and it’s a fascinating look at some of the people who have influenced your favourite geobloggers’ careers and scientific outlooks.
