BOOK LIST AND NOTICES100

Meeting 20th September 7.30 at Keswick Friends Meeting House

A table has been booked at the Cassa Bella restaurant in Keswick for 6 people including the speaker before the lecture. We are now unable to book a large table together so if anyone would like to organise booking their own table there is an online booking system at www.casabellakeswick.co.uk

The booking form has a ‘Notes’ box so it may be worth asking for a table near the table that’s already booked or at least ask to be in the same room. (Booking Ref RVWWDF in the name of Bethan Steele from 17.45pm). We hope to see you there.

Event Reminder: Coombe Crag Gorge

Saturday, September 16, 2023    10:00

Leader Steve Rozario

Meet at 10.00am at  Banks East Turret Car Park: https://www.english-heritage.org.uk/visit/places/banks-east-turret-hadrians-wall/directions/ £2 parking charge, free for English Heritage members.

The purpose of this excursion is to examine the regional geology and the sedimentology of the Leahill Cyclothem, a minor Yoredale Group cyclothem, and the picturesque, postglacial incised Coombe Crag Gorge, near Brampton. Full details of the excursion will be published in the new Geologists’ Association guide to Cumbria. The excursion is a 6 km walk on waymarked public paths, with 200m of ascent and descent, and will take about 4 hours. The paths can be muddy when wet, there are sections through woodland with exposed tree roots and paths along the sides of a steep river gorge. One section has steep drops on both sides and may be difficult for vertigo sufferers, although this can be bypassed if needed. Boots or stout walking shoes should be worn. A packed lunch is recommended.

We will see:

– a short section of Hadrian’s Wall and a Roman Quarry

– a cyclothem succession of fossiliferous marine limestone, offshore mud, and a prograding delta.

– channel sandstones and overbank deposits

– a gorge carved by glacial meltwater with an incised meander

Event Reminder: Graptolites at Dobs Linn

Change of date Dobs Linn is now on Saturday 2 September.

Excursion Document

This content is for members only.

Meet at 10 am outside the Visitor Centre in the Glenridding Car Park. Parking costs £8.50 for a full day ticket. If the car park is full, there are others at the Patterdale Cricket Grounds, and Patterdale Hotel.
The day will entail a roughly 6 km walk. The route from the carpark to the Greenside Mine is a very easy road track. Following the circuit route over a foot bridge, the route will diverge from the path to observe exposures that crisscross up to a disused slate quarry. This part of the excursion will involve walking over inclined, uneven ground and step over a very small stream. This late into the summer, bracken may need to be trampled. Once the geological discussions have concluded, we shall rejoin the footpath and return to the carpark. Depending on weather/enthusiasm etc the trip will last 4 -6 hours.
