We’re back down from the trek and can finally reveal the exact maximum altitude: 4620m (15157 ft)

Thanks a lot to all the participants. The closest guess is from

Bert aka Gert Büller from Dresden (4500m)

Congratulations!

This was the task:

We are in the Himalayas. And now it’s again time for guessing, only we don’t know the answer either … to the question, which altitude will our noses reach at the highest point before we go down to the valley again? Whoever guesses best wins.

P.S. We are currently at 1918m / 6290ft, we want to go trekking, Matthias has slight stomach pain, I’m rather heavily involved in digestion problems, but my cold is almost gone, in roughly two weeks we’re heading to the next country.
