There are ancient water channels that collected surface water on the Temple Mount leading down to the temple itself in the southern area are now 30 to 40 feet below the ground level of the mount today.

Archeologists reported in 2002 that one of the walls ( I think it was near the western wall) was bulging and in danger of collapsing.

It's very odd that these close-up pictures of the crater don't appear in the original news stories.

If that crater has pre-existing water in it, I think it's very significant, when it comes to the structural instability of the Temple Mount and I think there was some biblical prophecy that had to do with water coming from the Mount. Maybe someone can clarify this.
