High rock platform, Gribun, west Mull

 Scottish Sea Levels
4. Rock platforms of the west coast

Jura

By the 1970s, the new approach to Scottish sea levels, which had previously focussed largely on eastern Scotland, was turning to studies of changes in western Scotland, where the raised rock platforms had been a source of interest for some time. Studies here (e.g. Sissons, 1974) disclosed at least three levels, although any of these could have been a composite level reached on one or more occasion. However, most interest centred on the Main Rock Platform, the altitude of which appeared to slope downward towards the west and south-west, and which was associated with the cold climate episode of the Loch Lomond Stadial (Younger Dryas). The Main Rock Platform was correlated with the buried gravel layer in eastern Scotland, and today these are referred to as the Main Lateglacial Shoreline.
