Excursion Details
Details of this year's field excursions may be found below.

Please note the following general points:


Whilst there is normally no requirement to book, it is helpful to know in advance who will be attending so that an adequate number of handouts can be prepared. Also, if available, handouts can be sent beforehand to those interested. Please contact David Holmes (Tel: 01423 888997 - a message on the answer phone will suffice - or e-mail: holmsey@talktalk.net). Please provide a contact telephone number so that if there should be a late change in plans, David can phone you. If subsequently you find that you cannot attend, please let him know. Occasionally, numbers are restricted and you must book beforehand. This is noted below where relevant.

On the day, if you are lost or are held up by traffic, David can be reached on: 07531210691.

The LGA makes no charge to members for attending field visits but occasionally a charitable third party may seek a small donation. Where relevant, this is noted below.


Please share cars where possible as parking at some venues may be restricted - the notes below will indicate where this is particularly important. If you need a lift, please contact David who will try to help.


Safety is taken very seriously. Apart from the usual risks associated with walking over often difficult, rough or slippery terrain when out in the country or on the sea shore, there are those associated with examining geological features which are frequently sited in exposed or awkward locations. You should observe the Geologists Association's Fieldwork Code and seek the leader's permission before using a hammer and wear safety goggles. You must inform the leader if you leave early. Some meetings may be physically demanding. If you are unsure about your ability to participate, please let David or the leader know. Neither the leader nor the organisers are able to provide first aid. The leader has the right to refuse to lead any intended participant.


You should wear clothing and footwear suitable for the weather expected on the day eg waterproofs if wet and sun protection (plus liquid) if hot and sunny. You should also be prepared for a change in the weather and adverse ground conditions. Most if not all of the day will be spent outside. Walking boots and a packed lunch with liquid are required unless otherwise indicated. Hard hats and high visibility jackets are not usually required but see text below. Otherwise bring normal field gear such as lens, specimen bags etc. Binoculars are always useful.


The LGA has a Public Liability Insurance Policy which covers claims by:
  • Members and Third Parties against Leaders and the Association
  • Members against other members
The Policy also covers claims for damage to property caused by leaders and members.

Non-members who pay the day fee of £2 and sign the Attendance Register will be members for the duration of the Field Meeting.

The personal accident insurance cover for members is extremely limited and you may wish to take out your own policy to cover you in case of an accident.

You are responsible for your own safety and should have regard to that of others. You must follow the leader's instructions at all times. All members must sign the Attendance Register and provide a telephone number of who is to be contacted in case of an accident.

Visitors are always welcome. Apart from the event which forms part of the programme for Yorkshire Geology Month, visitors are required to become temporary members for the duration of the Field Meeting. Their subscription/day fee is £2 each.

Wednesday 7th June 2017 — Ribblesdale

Leaders: Mik Cardus (Unit Manager Tarmac, Dry Rigg) Gary Jaques (Unit Manager Tarmac, Arcow) and Bill Fraser (Leeds Geological Association).


These quarries both work steeply dipping and folded rocks of Silurian age; Dry Rigg the Horton Formation, Arcow the Austwick Formation. Rocks and structures will be viewed and examined and quarry operations explained. At Dry Rigg Quarry, which is surrounded on one side by Swarth Moor SSSI this will, dependant on operations, involve a walk into the quarry which has steep slopes as it works to a depth of 90 metres. At Arcow Quarry the newly installed railhead will seen. If time permits a visit to nearby Newfield Crag will be made to see the spectacular turbidites.

Geology: Silurian.

Practical arrangements:

Meet 10.30am at Dry Rigg Quarry car park. Postcode BD24 0EL. Grid Ref SD 802 694. Dry Rigg Quarry is at Helwith Bridge which is between Settle and Horton-in-Ribblesdale. From the south turn left off the B6479 At Helwith Brdge. Quarry entrance is on the right after 1km. Please reverse park, toilets available in the office, packed lunches may be taken in the education centre although limited seating. Hard hats Hi-vis jackets and safety goggles will be supplied at Dry Rigg Quarry. Finish 4-4.30p.m.

Sunday 25th June 2017 — The Chalk at Flamborough Head: on Foot and by Boat

The maximum number of participants is 29, booking is essential as we will fill the boat up with non-members if not booked, cost of the boat trip approx. £12. Please contact the Field Visit Secretary, David Holmes, to book a place on 01423 888997 (a message on the answerphone will suffice), or email holmsey@talktalk.net.

Leader: Paul Hildreth.


The morning session will be an examination of the stratigraphy of the lowest beds of the Burnham Chalk Formation (Upper Cretaceous, Turonian) including various flint forms at North Landing Flamborough and, if tides and conditions permit the topmost beds of the underlying Welton Chalk Formation. The afternoon session will be a boat trip from North Landing to Speeton and return. This will allow a view of the Chalk succession down to the Red Chalk and a close up of the Staple Nook deformation feature on the RSPB reserve at Bempton cliffs.

Geology: Cretaceous.

Practical arrangements:

10.30 am start in the large car park (TA239720) at North Landing (fee payable) toilets available. There should be time for lunch in the cafe, if required, between sessions, otherwise bring a packed lunch. Hard hats needed if you want to venture close to the cliffs, no hammering in situ but loose samples can be collected from fallen blocks. Cameras are highly recommended. Finish 3.30pm.

Saturday 12th August 2017 — Yoredale Cyclothems and Mineralisation

Leader: Brian Young, Honorary Research Fellow, Department of Earth Sciences, University of Durham. (Formally of BGS).


A walk of 8 kms along well graded woodland and moorland paths and minor roads, including a shortish steep ascent and similar descent, taking us along a stream section through 3-4 well exposed cyclothems within the Alston Formation of the Carboniferous Yoredale Group. Numerous features related to the area's formerly important lead and iron mining industry will be seen, together with several exposures of features of structural and mineralogical interest, including one of the most spectacular and instructive sites at which typical Northern Pennine mineralisation may be seen. The walk also provides good opportunities to relate the geological features to the local and wider, Pennine landscape, together with some interesting and regionally important woodland and moorland.

Geology: Carboniferous.

Practical arrangements:

Meet at 11.00 a.m. in the Car park on the north side of the A689 road on the west side of Westgate, Weardale, Co. Durham NGR NY906 381.

From the south take the A1 north to Scotch Corner, turn left on the A66 and, past Greta Bridge, turn right for Barnard Castle. Here turn right at the A67 junction, then left on the B6278 Harmire Road to Stanhope where turn left on the A689 for Westgate. Packed lunches and drinks to be carried, be prepared to carry clothing for all weathers.

Sunday 3rd September 2017   —   Castleton: Carbonate Platform Margins

The number of people on this trip is strictly limited to 15 since it is being taken jointly with The Manchester Geological Society. Early pre-booking is absolutely essential to ensure as many as possible of both Societies can attend. Contact David Holmes, Field Visit Secretary, on holmsey@talktalk.net or 01423 888997.

Leader: Dr Cathy Hollis, Manchester University.


An examination of the sedimentology of the northern margin of the Derbyshire Platform in the Castleton area. In the Lower Carboniferous, this region was located on the margin of a steeply dipping carbonate platform. Present day exposure within disused quarries and along public footpaths allows a cross section of facies from the platform top, across the platform margin and into the basin to be examined. The trip will involve walking on rough, but well-marked paths between Castleton, Cave Dale and Pin Dale roughly 3.5 miles.

Geology: Carboniferous.

Practical arrangements:

Meet for 10am outside Tourist Information in the main carp ark in Castleton ( SK150829 ) postcode S33 8WPwith public toilets, bring a packed lunch and drinks to take with you. No hammering is allowed, hard hats should be worn near to the cliff faces in Pin Dale and Hi Viz jackets are advisable on roads especially if visibility is poor. Handouts will be e-mailed to participants beforehand finish at 4pm.
