Spring 2010

CHAIRMAN’S MESSAGE

There have been positive comments about the newsletter, which will be produced four times a year and sent out to all members. There are various WYGT activities already planned for the spring and summer, so we hope to see some of you there.

The guided walks give you an opportunity to visit Local Geological Sites in various parts of the county and look at a variety of different rocks and fossils, guided by one of our members. We are very grateful to the West Yorkshire local authorities who include us in their countryside walks programmes. Their advertising means that we are able to reach many walkers and countryside enthusiasts who would like to know more about the geology of this area.

We enjoy activities aimed at children and young people and have arranged two Geodays for school holiday times, one during the Easter holidays at Bracken Hall, Shipley and one in the summer at Anglers Countryside Centre, near Wakefield.

The next general meeting takes place on Saturday 6th March. It is very short and is confined to WYGT’s activities, as we cover the business side of the organisation at executive meetings. We also include a short field trip to an Local Geological Site, so you are very welcome to join us. Details are found in the newsletter.

PROJECTS

WYGT is continuing to update the database of Local Geological Sites in West Yorkshire. This winter five surveyors are monitoring 32 LGS in order to assess whether the site needs management to improve its condition and to maintain its geological or geomorphological interest.

Sites in the Wetherby area are being investigated with a view to designating three sites as Local Geological Sites. Two are in the Permian dolostones and one site shows a glacial moraine. WYGT has received a grant from Natural England, through the Yorkshire and Humber Regional Geodiversity Forum, to finish the designation process. We are continuing to work with Leeds City Council’s warden at Otley Chevin to promote the geology and heritage of the Chevin, working with the Friends of Otley Chevin. We have written a geological guide which is linked to a short walk which will be marked by carved stones. An audio trail will be produced this summer and renewal of the interpretation board at Surprise View is still to come.

We hope to be part of a large project, covering the Southern Pennines, funded by the Heritage Lottery Fund. If the project gets the go-ahead in March we will be able to interpret six geological sites on the high Pennines during the next three years.

THREE NEW LOCAL GEOLOGICAL SITES IN WEST YORKSHIRE

The original 70 geological sites in West Yorkshire were surveyed during the 1990s but WYGT is always looking for new sites that represent the rocks in the county. We have researched three areas around Wetherby this winter and the new sites will be designated as LGS in the near future. Full details will be available on the website.

The Wetherby area has Upper Permian dolostones, which are part of the geological series that used to be called the Lower and Upper Magnesian Limestones. They form a ridge running north-south through the Vale of York from Sunderland to Doncaster, which has provided building stone for many villages and towns, including York. These yellow and grey limestones outcrop along the east side of West Yorkshire through Pontefract and Knottingley and have been quarried for road stone and agricultural lime for centuries.

Wetherby Riverside Cliffs is a cliff of Cadeby Formation dolostone adjacent to the River Wharfe. The cliff is about 150m long and 5-8m high and was probably carved by the river during high flow conditions, possibly during the last glacial event. The dolostones are very regularly bedded yellow and cream limestones which were precipitated in a very shallow, warm marine environment.

Boston Spa Riverside Woods are owned by Boston Spa Parish Council who are going to position interpretation boards, showing wildlife and geology, in the woods. Large algal reefs in the Cadeby Formation are best seen from the east bank of the river Wharfe near Thorp Arch.

Walton Moraine is close to the village of Walton, near Wetherby, and is important because it is part of the large Escrick moraine system which was deposited during the melting of the Vale of York glacier about 12,000 years ago.

FORTHCOMING EVENTS

Folly Dolly Falls, Meltham, near Huddersfield

The rocks of Huddersfield’s famous waterfall

Sunday February 28th 2.00 – 4.00 Organised by Kirklees Council

A short walk along the Meltham Greenway to see a waterfall formed by sandstones and mudstones.

Meet Alison Tymon at Morrison’s car park, Meltham HD9 4NL (SE 101 108) at 2.00 below the steep

rock exposure.

Buses from Huddersfield to Meltham reach the bus station behind the Library, which is a short walk

from Morrison’s supermarket. There is a steep, muddy path and a stone stile to negotiate so there is

no wheelchair access. It is advisable to wear wellington boots, as it is necessary to wade in the

stream in order to see the waterfall. Families are welcome, but children should be accompanied by

a responsible adult.

Roundhay Park, Leeds

Saturday 13th March 1.30 – 4.00 Organised by the Friends of Roundhay Park

Meet Bill Fraser outside the Mansion House Visitors Centre LS8 2JL at 1.30 pm (SE 330 383) in

Roundhay Park. A guided walk of approximately 1.5 miles around a marked Geological Trail taking

about 2.5 hours, with stops for discussion. Features seen are shales and several different

types of sandstone (some of which contain fossils), as well as sedimentary and tectonic structures.

Footpaths are graded for easy walking but can be muddy in wet weather.

Frickley Country Park, South Elmsall, Wakefield

Rock around Frickley Colliery – a walk around the landscaped colliery site

Saturday 13th March 2.00 – 4.00 Organised by Wakefield Council

A short walk of less than a mile to see the recently landscaped Frickley Colliery site, now turned into

a large country park. The restored site has many geological features of interest, including large

boulders of local rocks, which can be easily examined with a hand-lens, and a footpath indicating the

depth of Coal Shaft No 1, showing which coal seams were encountered.

Meet Alison Tymon and Rick Ramsdale at the car park (Grid Reference SE 477 100) on the B6422

about half a mile south of South Elmsall railway station. Footpaths are graded for easy walking.

Bracken Hall Countryside Centre, Baildon, Shipley

Wild Wednesday – Geoday – geological activities for children

Wednesday 14th April 2.00 – 4.00 Organised by Bradford Council

Dinosaur, rock, mineral and fossil activities for children of all ages

Bracken Hall Centre is on Glen Road, Baildon, Shipley BD17 5EA (SE 131 390)
