Re: Navigation, maps and TL
Area Knowledge seems to be the skill that jumps out at me here.

Re: Navigation, maps and TL
Navigation is almost certainly a TL1+ skill. At TL0, you're using Area Knowledge and simply taking the modifiers on p. B176. I'd use the -2 to -4 for going up one or two area classes in this case, since the people in question had to walk through the known area to get there and then through that unknown area, too. I'd also allow bonuses from complementary skills (e.g., Survival or Tracking) and for assistants. And for that matter, Tracking in itself could work . . . that's what "backtracking" is about.

GURPS Low-Tech p. 45 gives TL0 for the earliest maps and TL1 for scale maps. Low-Tech pp. 50-52 has the TL0-4 rules for navigation and specifically calls out Area Knowledge instead of Navigation at TL0. I'm not sure why you are looking in High-Tech for rules about TL0. High-Tech is TL5+, explicitly. |

I guess I'll have to look at Low-Tech and Companions eventually too. |

Also, people seem to be able to dead reckon their way back but lose this ability if they sleep.

Re: Navigation, maps and TL
That's more a problem with the rules for navigation than a problem with the rules for maps; maps that let you reliably go from an arbitrary position to another arbitrary position probably are TL 5, but following a trail, or going from landmark to landmark, is not, and a landmark map is much lower tech (an archeologist friend once showed me a Roman map of the empire. It was basically a link map, showing which cities connected to which cities, and how many days of travel, almost totally disconnected from the actual coordinates of the places).
