Our area covers over 1200 km squares and is roughly defined by the northern watershed running from Black Hambleton to Saltersgate; the Whitby to Thornton-le-Dale road to the east and the drove road along the edge of the Hambleton Hills to the west.

Our southern boundary is less easy to describe but generally includes the Howardian Hills as far as Malton and the Kirkham Gorge, following the 70 grid line.
