North of the village of Grassington, near Skipton in west Yorkshire, is a large field known as High Close Pasture, largely occupied by old cultivation areas separated from one another by lynchets and low, wide banks. The area so occupied runs 1200 feet in a northerly direction, and is roughly 300 feet wide. Formerly it extended considerably to the west, as remains of apparently the same series of lynchets are to be seen covering Kimbergill Hill and extending to the southern slopes of Lea Green. On High Close Pasture the lynchets and banks are well preserved ; they enclose rectangular fields among which, though varying in size and shape, the form of a short, broad strip seems to predominate. It is extremely difficult to deduce the dimensions of a customary acre from the actual fields on the ground? but in this case the strips average from 360 to 400 feet in length, and round about 75 feet in breadth–dimensions which suggest a I × 5 acre with an area of about 0.65 acre.
