Quite a facinating article about this subject and the potential size is pretty amazing. Possibly bigger than the Titanic or the Bismark, the question
they are now asking is would a boat/ship that size of wood actually float?

Images taken by aircraft, intelligence-gathering satellites and commercial remote-sensing spacecraft are fueling an intensive study of the
intriguing oddity. But whether the anomaly is some geological quirk of nature, playful shadows, a human-made structure of some sort, or simply nothing
at all remains to be seen.
Whatever it is, the anomaly of interest rests at 15,300 feet (4,663 meters) on the northwest corner of Mount Ararat, and is nearly submerged in
glacial ice. It would be easy to call it merely a strange rock formation.

"I'm calling this my satellite archeology project," Taylor said. It's an effort that has now included use of QuickBird, GeoEye's Ikonos
spacecraft, Canada's Radarsat 1, as well as declassified aerial and satellite images taken by the various U.S. intelligence agencies.

I feel if there was an Ark, then it was really a localized flood or tsunami that was attributed to God. That is the only possible way to hold "all"
the animals in my mind. A region of them yes, a planet of them no.
I'm pretty sure there is no evidence of a world-wide flood, but plenty of cases of regional flooding.
