Ron Wyatt, who has been telling his tales of discovering Noah's Ark, the chariots of Pharaoh, the pillars of Solomon, the true Mt. Sinai, the tomb of the Patriarchs, Sodom & Gomorrah, the place of Christ's crucifixion, and the Ark of the Covenant for many years, has been documented as an archaeological fraud. Both former "friends" as well as professional archaeologists in his own denomination (Seventh- Day Adventist) have published detailed refutations of all of his "discoveries."
There's an interesting page here, at NoahsArkSearch.com, that has some background info on the Durupinar site, a number of links to articles (mostly con, but also pro), and some interesting pictures. Check out the "Other Canoe/Boat Shapes" pictures, illustrating that this type of formation is not unique in the area.
Now that's just a sample of the creationist response. The real skeptics, of course, aren't any more favorably disposed to this fraud.
