Newmarket Ridge
The Newmarket Ridge is a ridge of low chalk hills extending for over 20 miles, from Bishop's Stortford in Hertfordshire to Bury St Edmunds in Suffolk, passing through the south-eastern corner of Cambridgeshire.
The highest point of the Ridge is Great Wood Hill at Rede (TL786558), the highest point in Suffolk.
The hills in this region tend to have quite steep sides but very flat tops, leading to very low topographic prominence. A case in point is Biggin Common, near the village of Castle Camps, where Cambridgeshire's couty top is found. Despite being a prominent landmark and the highest point for nearly 15 miles in every direction, its prominence is only 20 m to the marginally higher Great Wood Hill, 18 miles away, the hills being connected by a ridge of very little change in height.
