Please.
There are people in Tibet who live at higher altitudes.

According to this article, the average Tibetan settlement is 16,000ft.
And guess what - some of them have wooden structures in their settlements.
Finally, there is no evidence that this is a “large” wooden structure. Only a series of wooden structures embedded in rock and ice that spans some area.
So I’m still not sold. It’s the Old Man of the Mountain. People see what they want to see.
Yes, you are correct there are people who live at higher altitudes, as I found poking around the net after I posted. But only in areas where their ancestors have lived at high altitudes for 5,000 - 10,000 years (the Andes and Tibet, basically). There is no evidence that any of the peoples who live in the area (Turkey) have lived at those high altitudes for such a long time.
But, in the end, I didn't really disagree with you - there is no solid proof it is Noah's ark - just the possibility that it is a structure that would fit with the Biblical account and for which no other ready explanation is at hand.
