Early in 1904, whilst spending a holiday at Silverdale, near Carnforth, I noticed at the roadside near the Silverdale Hotel several heaps of a peculiar mottled limestone which was being broken up for road-metal. The resemblance to specimens I had seen from Derbyshire struck me at once, and I was not long in locating the quarry from which the material had been derived. The exposure of the rock is situated near the turn of an old cart track leading from Silverdale Green to Burton Well. When I visited the place there was a section visible of about 12 to 14 feet long and 2 to 3 feet deep. On the top was a thin layer of surface soil with vegetation on it. The floor of the quarry was also of the same mottled limestone. The strata here and in the immediate neighbourhood are rolling with a general dip of 10° E.
