The Ross of Mull is a comparatively low-lying peninsula exposed to the storms and swept by gales from the Atlantic. On these rocky shores are occasional stretches of sand which frequently have been driven inland, forming dunes and patches of blown sand at intervals around the coast. Sometimes the sand is forced up the cliffs and deposited more than 100 feet above the sea, and there are places in the centre of the peninsula where the blown shell-material is quite a noticeable constituent in the soil.
