Listen to the recording at Shewie's post.
Gave it a listen, nothing like it. And there sounded like half-dozen all in synch over-top of eachother like row-your-boat. High pitched but guttural with a little trill on the crescendos. Started at about 3am and went on for about an hour or so. Think heavy metal scream+horror movie scream+wolf howl and it's somewhere in there. Scariest thing I've ever heard and I've got a lot of dirt time.
