A number of small areas of Jurassic sediment occur in the western part of Area
8. The most prominent of these forms Dundry Hill (
d2
) on the southern edge of Bris-
tol. Dundry, rising to 233 m above sea level, is a flat upland made of limestones of the
Middle Jurassic Inferior Oolite. It is ringed by a broad zone where the limestones have
landslipped downwards on slopes of Early Jurassic (Lias) mudstones. In the eastern
part of Area 8, the surface is underlain by Early Jurassic mudstones occupying relat-
ively low ground, rising eastwards towards a scarp of the Middle Jurassic limestones
that define Landscape
F
, the Cotswolds.
