Grey Cairn from the NW, where the stonework is most free of vegetation. Image credit: A. Brookes (2.10.2012) thesweetcheat Oct 14, 2012
Thats pretty sizeable isn't it.
Yes, it's a couple of metres high, and I'm not sure how much more was hidden under the gorse. I'm also not sure if it's a long cairn or a round cairn, as the "long" axis isn't much longer than the width. Canmore seems to indicate no chamber.
