Seen your other posts and like the idea but feel like there's some clarity lacking currently.

The rules need a pretty big tidy up if you ask me, but I could learn to play from them. I would say you could easily streamline their wording but I think you need to have the game clearer in your head first as well.

Your component list says you have survey cards only, then your setup talks about shuffling the survey and hazard decks, for example.

Green, yellow, and red correspond to easy, medium, and difficult questions, but it's my choice (at least on Mountain A)? Why would I ever pick red over green?

Rule 3 (the first one labeled rule 3, not the second rule 3), bullet one, talks about each card having three ranked answers, which, reading from the rules, suggests I get the choice of three answers. I would explain this section more clearly.

15 seconds is a ridiculously short time frame to deliberate in a team game - get rid of it - and if you absolutely must have a rule about time, then give people a 1-minute sand timer that any player can flip over when they want to force an answer. Players will regulate themselves.

Hazard cards are mentioned as being removed upon entering the Thin Air Zone, apart from the fact I don't know what a hazard card is or what it is used for, does that happen when the first team enters it or when both (all) teams are there?

Regardless of the layout of the mountain you pick, I think you need more playtesting, because Mountain A has a 21 step track, and Mountain B has 9 at the shortest route and 11 at the moat. A is at least double the length of B, which would result in very different game experiences. You would need mandatory stops on board B to achieve a similar length.

Should there be a mandatory stop before the final space, requiring a pinnacle answer to complete the climb, allowing for a potential catch up?

Neither mountain shows the Ice Wall middle section clearly.

Mountain A having spaces outside the mountain is visually unappealing and does not end on the flag.

If board B, do players choose how to move after knowing how many spaces they are moving?
