In reply to Iain Thow:
> One of the weird things about Dartmoor navigation (in daylight obviously) is that when you first see a particular tor it often seems fairly close, but then it doesn't seem to get any closer for ages. Happens a lot, maybe something to do with them being the only landmarks, with bugger all in between to give them scale?
Very true!
We are on the South Moor tomorrow and apart from the volcano there are even fewer tors to give you a reference. Nav in these areas in poor viz by map only, no compass, keeps it all nice and interesting!
