The protective remains of soil and vegetation on the pillars was once continuous with that seen in background, and serves as an index to the amount of material removed by denudation. Once the protective cover is removed, erosion is rapid. Photographed about 1910 before the present-day tree cover was established. Glacial sands overlying boulder clay filling old valley and now being eroded by the present Rosemarkie Burn and by the direct action of rain, giving rise to earth pillars.
