Bring your secateurs and hedge trimmers to cut back the vegetation and clean up the outcrops, or just take the opportunity to visit the sites and talk about geology.Meet at 10.30 a.m. at Brown's Folly Car Park (G.R ST 798663). Strong boots, waterproofs & hard hats are required.
Saturday, 14th April
This excursion will examine the upper Triassic to Lower Jurassic sediments of the North Somerset coast with a variety of rock-types, a local abundance of fossils (hopefully) and tectonic features. Watchet is a classic location for ammonites (Arietes, Arnioceras), bivalves (especially Gryphaea) and reptile bones (e.g. Plesiosaurs). The section also shows dramatic tectonic features: faults, folds, deformation zones and slickensides, which could well be the result of subsurface salt movement (halokinesis), dissolution and stratal collapse.
At Watchet we will visit West Beach and Warren Bay to the west of the harbour where the Mercia Mudstone is well exposed with palaeosoils, gypsum nodules and veins, and interbedded sandstone. The overlying Rhaetic beds yield slabs of crinoids and bivalves on the foreshore, but they are locally intensely folded and faulted.
After lunch in the town, we will head east to Helwell Bay, a location noted for fossils but, to quote (https://ukfossils.co.uk): it is a bit of an unpredictable site. Sometimes, you can come away with nothing and other times a bucket full. Much depends on beach conditions. It is a good location for bones from plesiosaurs and ichthyosaurs, although fresh cliff falls are required.
Transport by private car; lifts to be arranged if possible.
Meet at the Watchet Visitor Centre, by the Railway Station, in Harbour Road, post-code TA23 0AQ at 10.30 am, where there is a pay & display car-park.
There is a small free car-park on the cliff overlooking Helwell Bay, at the end of a short narrow lane off Doniford Road, passed Watchet Football Club and just over the railway line (clearly visible on the Google satellite map). It is a 5-minute walk from there to the Visitor Centre.
This trip will examine the sarsen stones and landscape in the region of Fyfield Down.Meet at 10 AM in the walkers car park up the lane on the north side of the A4 (signed 'Manton' or 'Manton House') just west of Marlborough: Grid ref. 159 700.
We will do a three hour circular walk of about 5 miles around Fyfield Down looking at sarsen stones, including Clatford Bottom and the Stone Age axe-polishing stone known as 'the polissoir'.
After a lunch break we will meet in Avebury outside the Red Lion Inn at 2:30 PM and spend an hour or two looking around Avebury and it's building stones. The estimated finish time will be 4 PM.
There is a National trust car park in Avebury (pay & display for non-members) and as well as the pub there is a cage by the tithe barn, so plenty of choice for refreshments.
Saturday, September 1st
A continuation of the clean-up of the exposure of Greensand-Chalk, so come along with gardening tools. Strong boots, waterproofs and hard hats are required.Meet at 10.30 am at the Dead Maid Quarry Industrial Estate, Mere (ST 803 324) (further details will be posted here at a later date).
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.
