At least one 'wee cairn' is to a small child who sadly died in a road accident. Spoke to one person last time I was there who was putting flowers down for an elderly relative who was a keen hillwalker and loved this area. Pretty apt memorial and place for it I thought if you consider the view, which from Cairn O Mount (imo) is very special.

Don't know about down your way but I find it quite strange that lots of 'modern' cairns e.g. those built with stones and cement seem to appear on hills quite a lot up here, especially those dedicated to landowners and various lords and ladies in the 1800's onwards. Some of these people probably deserve their memorial but others are probably guilty of destroying circles and cairns etc., so somewhat ironic to have a cairn built to remember them.
