Picked Hill, Vale of PewseySome might think that the terraces on the side of Picked Hill in Wiltshire are livestock induced erosion. Historians tell us that these are lynchets, evidence of medieval ploughing techniques. A single direction plough was used, working around the conical hill, and leaving us evidence of ancient agricultural practice. This is also known as ridge and furrow cultivation.This image is copyright and may not be used without specific authorization. Permission is explicitly denied for Pinterest.
