While the adventurers are out of contact anyone can keep track of their route in real time using the Spot Connect website

If you zoom in using the satellite image rather than the map, you can see the nature of the country they are travelling through and generally see the rough tracks they are following.
Good fun for serious Sunken Miles neards (armchair adventurers)
