Cumberland Geological Society Presents –
From the Winter Lecture Events Programme:

A Visit to Crinkle Crags

7th September 10:00

From Three Shire Stone, Wrynose Pass summit. NY277027. Starting 10:00.

As the trip to Crinkle Crags is much more physically demanding than usual, those thinking about coming along should be given a good idea of what is planned. Your leader Clive Boulter has created a preview presentation of what can be expected.

The Crinkle Crags event will have a fine weather and poor weather alternative. Below you can find the two presentations.

Old Mines and Carboniferous limestone at Hodbarrow, Near Millom

Led by David Kelly on 13th August 2016

David led 20 of us past the remains of the Hodbarrow Mine on a dry breezy day. Its main ore body, the largest in Cumbria, measured 600m x 600m x 30m and was close to sea level. At first we walked along the flexible Outer Barrier with its watertight puddled clay core skirting the smaller Moorbanks ore body. The rigid Inner Barrier had failed so the main orebody area had flooded when the mine was abandoned. Our lunch stop was in the Red Hills Quarry in the eponymous highly dolomitised limestone. The beach at Haverigg Point had a very varied mixture of interesting erratics and highly coloured furnace slag and clinker. Our final stop was a fossiliferous locality in the Red Hill Limestone exposed in the faulted anticline. It had thumb length crinoid columnals and tennis ball cross sections of gastropods.

From the Summer Events Programme:

Event reminder for 13th August:

Old Mines and Carboniferous Limestone at Hodbarrow Near Millom

Located at Poolside, Haverigg, Millom, Cumbria LA18 4HW, UK

The clue is in the title.

Leader: David Kelly

Events are open to members and non-members. This event is free for members and non-members who wish to ‘try out’ the society.

11 members and friends of the CGS travelled by ferry to stay at Melrose House, Douglas where we were given an introductory evening talk on the general geology of the island in its Plate Tectonic context by our leader for the week, Dr. Steve Crowley of Liverpool University and each issued with a detailed booklet of the locations to be visited in the next three days. isle of man

Tuesday 12 July The main theme of the day was the events of the Lower Palaeozoic including the Lower Ordovician Manx Group submarine fan deposits exposed in locations around the south coast, late Caledonian deformation and regional low-grade metamorphism, Foxdale Granite magmatism and contact metamorphism and base metal mineralization.

Wednesday 13 July This day dealt with basic magmatism, the contact zone between Manx Group and mid-Silurian Dalby Group turbidite meta-sediments, mid-Silurian sedimentology, late Caledonian deformation and regional low-grade metamorphism, and Lower Devonian fluvial sediments of the Pele Group.

Thursday 14 July Our main focus on this final day was the sedimentology and volcanology of the Lower Carboniferous carbonate-dominated succession exposed around the south coast in the Castletown area.

Apart from two short but intense showers on Wedneday afternoon we enjoyed good weather and visibility. We are indebted to Fiona Harwood for driving us around in the hired  mini-bus, to Susan Beale for organising the visit and especially to Steve Crowley who constantly kept us informed and stimulated throughout a concentrated three-day period.
