Geoff and Steve cross the Arctic Circle and head north on one of their most daring expeditions yet. With the help of a brilliant Swedish meteorite-hunting family the guys will attempt to uncover ancient space rocks that were transported by glaciers during the last Ice Age, and which have remained hidden and buried for 60,000 years. As the Arctic winter approaches they have only a few days to test new equipment, explore the mysterious forests of Lapland, and try to solve the enigmatic puzzle of the Muonionalusta strewnfield.
