Description

FINDHORN TERRACES Findhorn Terraces is located in the Findhorn valley in upland Nairnshire. It is notified for its series of river terraces. The river terraces on the east side of the River Findhorn at Ballachrochin are unique in the number of levels preserved and are also exceptional in their height above the present river (approx. 70m). Locally, eight to eleven levels have been mapped, with several smaller units inset within larger ones. The highest terraces are formed from sediment washed out from glaciers, and there are kettle holes on the surface. Bedrock at the base of the lowest terrace has protected the higher terrace levels from erosion by the river. Other interesting features include the large height and width of some of the terraces. This represents possibly the highest and most dramatic staircase of terraces in Scotland.
