A small valley in southern England with an important series of loams and gravels spanning the last two glacial periods and intervening interglacial. Stone tools included Levallois flakes, but only a few hand axes and other tool types were found. The area has also given its name to a decorated pottery style of the Neolithic period. The first Jutes, Hengist and Horsa, landed at Ebbsfleet in the Isle of Thanet in 449 AD.
