Space.com is carrying this update on efforts to resolve the "Ararat anomaly:

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—that remains to be seen.

The effort to find out is being spearheaded by an associate professor in paralegal studies at the University of Richmond's School of Continuing Studies in Virginia, who seems, from quotes in the article at least, to be reasonably rational. Then again, questing for more than a decade to figure out if a somewhat distinctive collection of rocks is something else tends to make me wonder.

Maybe that's where the aliens are hiding?
