Extent and geology

The vale is a tract of low ground rising east-north-east, drained by the River Devon and its major tributary the Smite. Its vale-like form can be viewed either from its south-east to eastern flank (the Belvoir "ridge") or from the north-west along the A46 (Roman Fosse Way, which runs along the watershed between the Devon and the River Trent), from which it is less conspicuous.

The vale is the product of various geological processes. It is occupied in the main by the sedimentary mudstones and thin limestones of the Liassic (Lias), with a northern fringe from the upper parts of the Triassic (Mercia Mudstone and Rhaetic). The south-eastern margin is the most clearly defined because it is formed by a conspicuous scarp slope, on which Belvoir Castle sits about 330 feet (100 m) above the valley floor. Its resistance to erosion is due to a capping of relatively thick Jurassic Ironstone. The vale-like form is further constrained by cappings of ancient glacial till that form the higher ground along its western margin.

In the Pliocene epoch (1.7 million years ago) the Vale of Belvoir was occupied by the "Proto-Trent" River, which cut a gap through the limestone ridge at Ancaster and then flowed on to the North Sea. At the end of the Wolstonian Stage (c. 130,000 years ago) a mass of stagnant ice left in the Vale of Belvoir caused the river to divert north along the old Lincoln river, through the Lincoln Gap.
