Tors elsewhere in NE Scotland
Tors occur widely in NE Scotland, although only rarely do they reach the scale of the Cairngorm tors.
Granite tors, more or less modified by ice, are found on the summits of Ben Rinnes, Bennachie, Clachnaben, Mount Keen and Lochnagar, amongst other hills.
Tors developed in other rocks include Clach Choutsaich on Brown Cow Hill
(amphibolites).
Clach Choutsaich
The gabbro tors of the Cabrach are almost unique in their basin rim and low-lying setting. Deep grussification is common in this area (Basham, 1974). The numerous glacially-transported corestones that litter the Insch basic igneous mass indicate that tors were widespread there prior to glaciation.
