Beinn Liath Mhòr is a Scottish mountain situated in the mountainous area between Strath Carron and Glen Torridon in Wester Ross in the Highland region. Geologically Beinn Liath Mhòr is made up of Cambrian quartzite scree and Torridonian sandstones giving the mountain a distinctive colour contrast of light and dark. The mountain's other main characteristic is its two-kilometre-long undulating summit ridge which does not drop below 800 metres for its entire length. This culminates at the summit at its far western end at a height of 926 metres (3038 feet) making Beinn Liath Mhòr the 258th highest
