The project is a study of soil erosion within the cairnfields on the Eastern Moors of Derbyshire. A range of Archaeological features and natural sedimentary sequences were excavated in the search for eroded sediments. The erosion evident at these features was dated by means of radiocarbon and optically stimulated luminescence dating. Contrary to previous assumptions as to the scale of erosion in later prehistory, which maintain that this was a severe problem, it is concluded that the evidence indicates a low degree of erosion for the Bronze Age. Erosion is concluded to have increased from the Iron Age with the establishment of extensive pasture land.
