Site Visit and Conservation at Brown's Folly Nature Reserve
with the Avon Wildlife Trust
This is our annual clear-up of the geological sites on this SSSI Reserve. Come along with gardening tools or just take the opportunity to visit the sites and talk about the geology. Variable levels of activity depending on what you decide to do!
Meet at 11.00 a.m. Brown's Folly Car Park (ST 798694). There are some steep slopes; strong shoes and hard hats are essential.
We shall have a morning walk east of Camerton and then a drive to lunch at Combe Hay, where there is a pub with excellent food. In the afternoon we shall walk around the canal at Combe Hay. There are a reasonable number of exposures spanning Mercia Mudstone to Inferior Oolite, plenty of canal features, coal mine remains and links with William Smith. Copies of relevant archive maps and documents will be provided.
Meet at 10.30 a.m on the road beside Camerton Old Mine, grid ref. ST 681 579. Take the A367 from Bath towards Radstock and turn right on the B3115. At Meadgate, turn left towards Camerton. Parking in spaces along local roads. Lunch at the pub in Combe Hay. Walking boots or strong shoes essential because of muddy paths.

Chisbury Hill-fort: view of the wooded hills east of Savernake Forest, on the edge of the London Basin, where the Chalk is capped by a thin layer of Tertiary sands and clays.
Stype Wood: the Cretaceous/Tertiary boundary is marked by solution hollows where streams running down over clayey Tertiary beds on the hill-top disappear when they get down to the porous/permeable Chalk below.
Littlecote quarry: a solution pipe in the top of the Chalk can be seen to be filled with Clay-with-Fints.
Kennet & Avon canal: the canal will we followed from Great Bedwyn westwards, passing the Crofton Beam Engine -built to pump water into the canal at its highest point. Nearby, to the west, the canal goes through the brick-lined Savernake tunnel as it enters the Vale of Pewsey.
Vale of Pewsey: we will look at the structure of the vale and how it affects the bounding Chalk escarpments, with a stop at a pit in the Melbourn Rock at the base of the Middle Chalk.
Meet at 11.00 a.m. Manor Farm Stud, Chisbury - SU 280 660. We have permission to park in the farmyard: turn right after going into the farm entrance and go round into yard area to park (south-east side of the house). Walk to the redundant church behind the buildings.
As this is some 35 miles from Bath, those who want to share cars to reduce the size of the convoy to the next 5 localities as well as save on petrol, could meet at 10.15 and park on Spa Road, Melksham (by the 3 big spa lodging houses) where we met up for the field trip 2 years ago, GR ST 914 628, (behind the roundabout on the A365 southeast of Melksham on the road to Devizes - take road towards town centre/hospital at that roundabout, then turn sharp right almost immediately).
A member of the Bath G.S. committee will wait there until 10.15 a.m.
There will be a lunch stop in Great Bedwyn where there are two pubs. Hard hats and strong shoes will be required
We shall take a short walk along the prom to consider sea defences and beach restoration and there will be a brief review of what is below the Bristol Channel. We shall also walk through the woods to Greenaleigh to examine head deposits, the arcuate shingle ridge, Variscan/Tertiary tectonics and Devonian sediments.
Meet at 10.30a.m. Harbour Car Park, Minehead by the Lifeboat Station.

2004 saw Sherborne in the public gaze, thanks to the television programme "Restoration", which figured the elegant Sherborne House as badly in need of care and attention. The cause was the saving of inside wall paintings, but the stone exterior alone is a lesson in what-not-to-do in the case of heritage buildings. The streets of Sherborne are testimony to the excellent local Middle Jurassic limestone as a building stone - to compare with Bath Stone. We shall start at Sherborne Abbey and will follow a trail which picks up buildings and pavings that will interest.
Meet at 10.30 a.m. at the West Door of Sherborne Abbey. Bring a packed lunch or buy lunch in Sherborne.
