Description: From near the top of Cairngorm. Looking west. Inverness-shire. The plateau surface showing granite weathering out into blocks and disintegrating in situ on mountain top forming a blockfield. The Braeriach plateau in the distance. The blockfield is formed by 'periglacial' processes where frost and ground ice shatter the granite bedrock. The Cairngorm summits form the highest of a series of stepped erosion surfaces which are found across north-east Scotland. They date from the Tertiary period before the glaciers. Periglacial landforms are those formed by cold-climate non-glacial processes.
