If the rock behind Bin Laden was sedimentary, it would suggest that the area was underwater at some recent point in its history. I suspect only southern Afghanistan is at a low enough elevation to have been under a sea in the recent past.

Hmmmmm.

OK I'll throw in my few units of Geology.
Present elevation is not necessarily an indicator of past elevation.
I would say more "distant" past rather than "recent" past.

Personally, I remember those rock formations in two specific scenes from "Return of Planet of the Apes". I hope somebody is looking for Bin Laden here in the United States! JEEEEZZZ!!!
