How about how many Angels can dance on the head of a pin! :)

The Head of the Pin River is in the rather unhabited Parvati valley. Perhaps the angles are dancing there, along with the seraphim, cherubim, and thrones.

That should have been uninhabited. I didn't mean to imply that nuns couldn't live there.

You weren't referring to the Pinhead River, were you? ROFL!
