Field trip to Nannycatch Gorge

On 20th September a large number of members met at Kinniside Stone Circle on a rather windy morning.   Our leader, David Kelly took us into the upper valley of the Nannycatch Beck to an exposure of the Skiddaw Group.   This was the Buttermere Formation with cleaved mudstones which even in this relatively small outcrop had varying cleavage directions reflecting the olistrome nature of the deposit.   The party descended through the gorge to examine intrusions into these rocks.   After lunch, taken during a shower, David introduced us to the Latterbarrow Sandstone, a conglomerate thought to be the base of the Borrowdale Volcanic Group, visible in small exposures on the sides of Swarth Fell.    In addition to the solid geology the group also considered the curious drainage pattern of the Nannycatch Beck.  The final visit of the day was to the head of Combe Beck, with more curious drainage, with Skiddaw Group rocks intruded by dykes exposed in the beckside.   Thanks were given to David who had led us unerringly across pathless fells to such interesting sites.
