Field Trip: Wootton Bassett Mud Springs and Swindon Railway Cutting

Leader: Isobel Geddes, Wiltshire Geology Group

Entry Fee

Members: Free

Visitors: £3.00

Date and Time



Marlborough Road, Royal Wootton Bassett, Wiltshire, SN4

Field Trip Description

The Corallian limestone aquifer rises to the surface at Wootton Bassett where it collects rainwater. There is sufficient hydrostatic pressure at the lowest part of the adjacent downfold to cause upward movement of water through the overlying Ampthill Clay which becomes liquefied, emerging at the surface as mud springs. The Swindon railway cutting (SSSI) displays the Upper Jurassic Portlandian sequence and is very fossiliferous.

Meet at 10.30 a.m. at G.R. SU 071815, SE of Wootton Bassett, near the road to Broad Town. After crossing the railway, there is a track to the left, with adjacent car park, just at the edge of the town.

Important Notice: Bath Geological Society Insurance

Each person attending a field meeting does so on the understanding that he/she attends at his/her own risk. The Bath Geological Society has Public Liability Insurance Cover for field and indoor meetings, but Personal Accident Cover and Personal Liability Cover remain the responsibility and personal choice of the participant.

There may be an element of appropriate cover included in house insurance or in travel insurance: although Bath Geological Society activities are not particularly dangerous members are advised to check whether exclusions apply to activities in which they plan to participate in case they wish to arrange further cover. An annual travel insurance may be the best solution for any member who regularly attends field events: this again is a matter of choice.

Please note however that all members participating in overseas events will be required to have travel insurance for the duration of the event: this is so that participants are covered for Medical, Repatriation and Personal Liability expenses. The Personal Accident element remains the personal choice of the member and again members are advised to check exclusions so that they can make an informed decision about the cover they want.
