Red Point beach in the last light of the day. There are visibly distinct lag deposits / aeolian winnowing of the sand by 'colour' with heavier grains of red sand (presumably derived from red Torridon sandstone?) and lighter grains of pale coloured shell, quartz, feldspar and weathered grains. The Marram grass appears to concentrate the red coloured sand. Similar sorting of sand by colour also occurs in the littoral zone with bands and patches of distinct colour.

In the image are the exposed roots of the Marram grasses where a dune blowout has taken place and visual indication of how the grasses consolidate dune systems.
