Walk along footpath skirting railway (over London Clay) to West Horsley.

Walk southward via Pebble Hill, where there is a small Tertiary outlier, to Netley Heath. Examine sand pit at about 620 O.D. The sand is much disturbed in places and contains a good deal of ferruginous grit, frequently in the form of hollow nodules. This grit contains numerous flint pebbles but otherwise resembles that of the Lower Greensand, fragments of which are also present. Iit also occur occasional imperfectly preserved casts of marine fossils, and the deposit has been correlated with the beds of Pliocene age at Lenham.

Page 37 P804703 Coombs Chalk Pit at West Horsley, Surrey. A section in the upper part of the zone of Micraster cor anguinum [corangium]. Excursion to Horsley, May 23rd 1914. There are two sets of strong joints running roughly NW to SE and NE to SW which causes the faces to be smooth and almost vertical. The Chalk is white and hard with well marked bedding planes and nodular flint bands at varying intervals. Not far from the top is a thick yellow bed. Added note: Walls 50 ft. high.
