The Glacial Drift at Finchley

Nature volume 5, page 27 | Download Citation



A FURTHER examination of the railway cutting at the Finchley and Hendon Station shows that the glacial beds now revealed there have a greater thickness and range than I at first imagined. On Saturday last I visited the place in company with Dr. Hicks, of Hendon, a gentleman well-known for his researches in the Cambrian formation. Above the blue clay, and right up within a few inches of the vegetable soil, we found drift fossils. With an interruption here and there from the underlying London clay, these chalky glacial beds, consisting of blue (Oxford?) clay, blueish clay with flints, marl, sand, and gravel (in no regular descending order), have an average thickness of 30 feet. They are open for about 500 yards, and they might perhaps be traced farther north-west, towards the Dollis Brook Viaduct. Dr. Hicks and I afterwards visited Mr. Plowman's Manor brickfields, a little south-east of the railway station; here too we found fossils in the brick-earth.
