It’s really strange the fact that, after you went multiple times in the same zone, you still find little details to adjust on osm the next time you are there. Maybe you can add some surface, maybe there’s a little path you never went through, maybe you discover a little spring you never noticed.

I think the optimal way to handle this kind of “zones” would be to reside there for 1-2 weeks and complete it (if that’s even possible).

It still remain awesome the feeling of unknown you have in the mountains, where there are hundred of little paths that nearly nobody have used in the last years. I really feel like an explorer!
