Tabular Hills

The Tabular Hills are an east-west line of distinct hills on the southern boundary of the North York Moors, running from Scarborough in the east to Black Hambleton in the west. The name refers to their flat, tabular summits composed of hard Corallian limestone known locally as "nabs". They form the northern boundary of the Vale of Pickering.

Steep-sided river valleys break through the Tabular Hills to form a broken series of tablet-shaped hills. The most distinctive feature of these is their northern escarpment, which rises to 200 ft above the moorland to the north. At their western end, beyond the River Rye, they join with the north-south Hambleton Hills, which have a similar geological basis.
