The Lincoln Edge, or Lincoln Cliff as it is also known, is a limestone escarpment that runs roughly north-south through Lincolnshire.
Never rising more than 150 feet, the Lincoln Edge runs from just north of Grantham in the south of the county to the Humber Estuary in the north.
Made of oolitic limestone, the Lincoln Edge is a continuation of the Cotswolds and then continues on into the North Yorkshire Moors.
The escarpment south of Lincoln overlooks the Trent Valley.
Villages are found on the spring line roughly a mile or so apart.
Old cottages in the centre of these spring villages will be very familiar to anyone who has wondered around the Cotswolds, the same warm stone.
The dip slope, until Napoleonic times was open desolate heath. This is still reflected in many of the place names.
The Lincoln Edge is broken at Lincoln at the Lincoln Gap where the River Witham breaks through. On one slope the cliff edge village of Washingborough. On the other slope the ancient city of Lincoln, dominated by the Norman Castle and Cathedral.
Perched at the far northern limit of the Lincoln Edge is the remote village of Alkborough, overlooking the upper reaches the Humber Estuary.
The Lincoln Edge can be best appreciated on the main East Coast line as it passes through Grantham towards Newark. Approaching Grantham it becomes very hilly. Passed Grantham, the Lincoln Edge can be seen receding away in the distance. The railway line once used to follow the Lincoln Edge on towards Lincoln, but alas no more. To get to Lincoln by train, it is now necessary to change at Newark.
