Periglacial phenomena on the Island of Rhum in the Inner Hebrides

Synopsis The mountain areas of Rhum, developed in Tertiary volcanic rocks, exhibit various landforms and deposits of periglacial origin, the most important of which were formed by cold climate geomorphological processes during the later stages of the Late-glacial period. Blockfields were developed in the west, in well jointed granophyre; in the east there are frost shattered tors, an altiplanation terrace, and huge screes were initiated below all the steeper higher peaks. Contemporary processes continue to produce screes and induce solifluction and the development of small scale patterned ground.
