The Durupinar site is just 2 miles from the northern Iran border, and the skirmishes on the border involving Mt. Ararat make the government reluctant to approve archeological work on Ararat itself and may be a reason for Turkey and Ataturk University's earlier seal of approval for this place 17 miles away from the military forbidden zone of Mt. Ararat.  Here's the famous Life Magazine picture taken from an aerial survey plane from 10,000 ft.

  The site doesn't seem geared toward tourism dollars; there are no obvious road signs to let you know the ark site is there, and the road going up to it is just barely navigable, to put it nicely.

  I had very little time inside so just took photos of some of the articles on the walls so that I could read them later.   Here's an online article of Pros and Cons (more the latter) with pics.  And History Channel's documentary from 2001 includes pictures and comments on this Durupinar site which are interesting.

  An analysis of samples from the area, in 1996, quite thoroughly debunked most of the physical ark theory, though several features of the formation had been convincing to an archaeologist at Ataturk University and some U.S. geologists.   The debunking article by Lorence Collins of California State University Northridge raises an interesting question:

"David Fasold suggested that, although the structure is not Noah's Ark, it may very well be the site which the ancients regarded as the ship of the Deluge and may have played a role in the Flood story.  As a geologist, I find this to be an interesting speculation."

  At least, the area has great views of Mt. Ararat and the limestone range thought "as high as the wall of heaven" in The Epic of Gilgamesh.

  Possibly the most interesting related event was David Deal's discovery of a settlement above the site and another seeming-boat imprint there, which could be, he writes, "The place of first descent" ('kHD' or Kurd) with the Durupinar site being the last one.  "Recent travels to the Iranian Frontier of Eastern Turkiye" is about a workshop for explorer-participants with Dr. Salih Bayraktuhan of Ataturk University, who oversees geological and archaeological studies for this region, and David Deal.

  Those geologists still entertaining the possibility this is the ark site feel it's more likely a mold of the hull of the ark, a footprint of a landing, rather than the Ark itself (assuming one believes the ark story itself is real).  The recent History Channel video seems to leave things a bit open.
  If further interested in this at least very colorful story, here's a book-length history of their ark tribulations by Wyatt's widow; two free online 1-hr videos about the site; and the best arial photo I've seen of the formation (even if solidified mudflow).  Also, another tourist visit there with better photos.
