Chris Rowan is a geologist specialising in the dark arts of paleomagnetism, and getting people to pay him to travel to exotic destinations for fieldwork. Having drilled up New Zealand during his PhD, he is now a post-doc at the University of Johannesburg. 
Well, after just enough time to get all my laundry done and sort the chaff from my e-mail account, I'm off on another field trip. This time I'm heading to north-west South Africa for a week and a bit with the 4th year students. It should be fun - if possibly a little chillier than balmy Barberton (to my English seasonal tastes, there's something faintly wrong with being able to wear just shorts and t-shirt less than a month after the winter solstice).
So apologies for the extended hiatus - although hopefully I'll have some cool photos to show off when I get back. In the meantime, fell free to continue the geological variant of Mornington Crescent - I'm finding it entertaining, even if no-one else is. There's also a couple of items for discussion popping up in the next couple of days: one frivolous, one less so...
