Geological Period: Quaternary
Description
Area,3.7 hectares 9.1 ac Description Harrow Weald is a small but important geological site which exhibits the most complete exposure of Pleistocene Gravel Beds overlying the Claygate Beds. The Pebble Gravels are of uncertain origin and this has been the subject of much controversy over the past century. Recent research has cast doubt on their marine origin which was inferred by most early workers. The Harrow Weald section is important as a key site on which to base further studies of these deposits.
