I had exactly the same thought Chris but the ones on SCWiki are definitley below the Corrie (we did see a couple on the flog up across the scree into the corrie whereas my photo is of a boulder actually in the Corrie - not certain the bridge flagged in that SCWiki photo is there still either
If you look at the high and Dry boulder in the photo it sits under the right shoulder of the Corrie and the one I saw is at the base of the cliffs in the corrie bottom itself - imagine a spot halfway between H&D text and the Bridge text but significantly higher up the hill than H&D text in the photo - sorry not being very accurate here, I'll try and edit the photo from SCWiki to show what I mean but cant post from work on Flikr so PM an email addy if you want it from info/reference
Anyone thinking of having a nosey I suggest a route up to the corrie from directly below - contouring the scree slope is purgatorial and not reccomended
