There wasn't a "mudcat" in that URL, but somehow it kept getting added in. I hadn't put the "https:" part in though, so it was doing its own thing, I guess. Anyway, now it's there twice.

It's pretty amazing that anything was there and in such condition if he was exposed several times. They say that because of much newer things found with him, he was exposed, but there is another easy answer: perhaps those things were suspended in the ice above him, and as the ice melted they descended to his level. I spent a lot of time climbing on glaciers in my late teens and 20s - any dark object on the ice surface warms and sinks and you can see pieces of rock, etc., in shallow depressions or deeper holes, depending on how long they've been there.
