Members of the Society from 1991 to 2010

Barnoldswick: Sept, 1991
Our inaugural field excursion based in and around Barnoldswick.  We began in Letcliffe Park.  This gave us an opportunity to take in the regional geology. From the park you can see over the Craven Basin towards Malham and Settle. The drumlin field around Hellifield is fairly easy to pick out.

Chatburn Limestone: type-section for the Chadian Stage
The name Chadian was derived from the nearby village of Chatburn which was itself named after St.Chad, the Bishop of Lichfield.  Outdoor field excursions are held from April to September, the majority of which are organised by members of the society. Photo: Yvonne James


Crummackdale, Austwick: May, 1999

Nappa Scar
Nappa Scar is a key locality in the Lower Palaeozoic inlier which shows an exposure of the Sub-Carboniferous unconformity in Crummackdale.

Pebbly limestone and conglomerate onlap a palaeocliff in cleaved calcareous siltstone of the Upper Ordovician (Ashgill) Norber Formation.

The Volcanic Succession on Brown Knotts by Derwent Water
Brown Knotts is representative of pre-caldera volcanism in Borrowdale Volcanic Group and an internationally important example of dissected plateau-andesite province. Even CPGS have to make the best of poor weather! Photo: Yvonne James

Whin Sill, Teesdale: July 2007


Whin Sill at Higher Force, Teesdale
The Whin Sill, which is a quartz dolerite, is one of the main natural heritage features of the North Pennines. In fact it is the original sill of geological science. It takes its name from the north of England quarryman's term 'sill' meaning any more or less horizontal body of rock, and 'whin' meaning a hard, rather intractable, black rock.

Whin Sill
Here at Low Force the Whin Sill can be examined closely. At this locality you see the top of the Whin Sill. Spectacular polygonal jointing is well displayed.

South Craven Fault: August, 2007


South Craven Fault
The walk along the fault scarp offers superb views of the Craven Basin. The Lower Haws and Gordale limestone of the scarp contrasts with the millstone grit (Grassington Grit) expoded in knolls to the right amongst the lush green grass of the Ribble Valley. Photo: Paul Kabrna

Stalagmites & Flow Stone in Ingleborough Cave
The cave is one of the highlights of our walk from Clapham village centre to Gaping Gill. Other features of the walk include crossing the South Craven Fault and the North Craven Fault, the Carboniferous basal unconformity at Cat Holes and the narrow gorge-like feature of Trow Gill.
