That Southern Vatten cairn "hovering in the background" is none other than the delightfully flat topped MacLeod's Table North (also known as Healabhal Mhor) which is a mountain 470 metres high and five miles away. The two Vatten cairns very much reflect the appearance of the two Macleod's Tables on the Duirinish peninsula's skyline across Loch Bracadale.
The Southern cairn isn't in your photo, but would be somewhere behind and to the left of the North one in your picture!
