A (~ 4km) walk around the southern slopes of Pen Hill where there are rocks from four geological periods – Devonian, Carboniferous, Triassic and Jurassic.

Meeting location will be provided on registration.

There is an old quarry in a private garden with outcrops of the CDL showing a bed with an erosive base and another bed with probable stromatolite/algal mats. We will also see a narrow gulley showing red Mercia mudstone overlain by a thin green mudstone layer (Blue Anchor?) and then into Triassic lsts (White Lias). Further up the track is another quarry but this time in a Blue Lias sequence. Not many places to see this transition in the Mendips.

At the start there is a very nice valley (called The Combe and owned by large house Milton Lodge). There are some Triassic conglomerates exposed in upper part of the valley.

One negative point, the group would have to cross the trunk road (A39) three times where there is no speed restriction!

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.
