Geology
Pitcombe Parish
In the heart of the parish is a plateau shared with Shepton Montague, which is interrupted by two steep-sided valleys, that to the east, formed by the river Pitt, the site of the settlement which gives the parish its name.
The central plateau is of Inferior Oolite whose highest point is Pen Hill (150 m. (481 ft.)) on the boundary with Shepton Montague immediately north of Hadspen House and the lowest is at Cole in the Brue valley (51 m. (194 ft.)). Spurs in the west above the Hadspen valley reach 120m. (460 ft.) and in the east Cliff Hill, south of Godminster Farm, reaches 110 m. (420 ft.). The two valleys, with streams draining north-east and northwest into the Brue near Cole, are formed of Midford Sands, and bands of Fuller's Earth clay and limestone run along the eastern edge of the parish and near Hadspen House.

Shepton Montague Parish
Much of the northern and part of the southern boundaries of the main part of the parish follow streams which flow into the river Brue. From the main stream and its feeders in the centre of the parish below the 70-m. contour the land rises to just over 400 m. on the boundary with Bratton to the south-west and to more than 450 m. in the west above Hadspen, all on limestone and clay with Fuller's Earth. In the centre of the main part of the parish is a small ridge of Forest Marble clay just over 120 m. above O.D. The clay ridge continues north-east to Stoney Stoke, where at a height of 114 m. it merges into Cornbrash limestone. The detached areas further east lie first on undulating ground over Oxford Clay and then on clay and greensand rising sharply to 793 m. on the Selwood ridge.
