The hills are made up of rocks of middle and late Jurassic age with the hard Corallian Limestone forming the cap at the highest points.
The highest point is Black Hambleton which rises to 1,308 feet (399 m) at the northern end of the range.
[1] The Corallian Limestone also outcrops along the southern edge of the North York Moors forming the Tabular Hills which run from Black Hambleton eastwards to Scarborough, although much broken through by river valleys.
In the 12th and 13th centuries, the Hambleton Hills was the production centre for York Glazed Ware, a type of Medieval ceramic.
[4] The vet Alf Wight whose pen name was James Herriot, famed for the All Creatures Great and Small series of books, TV programmes and films, lived and worked in the nearby market town of Thirsk, and many of his stories take place in the Hambleton Hills.
