Excursion to Clandon, Newland's Corner, and Silent Pool. Saturday, May 11th, 1912. (Transcription from GA Circular No. 144. Session 1911–1912. p.2-3)[edit]

DIRECTOR: GEORGE W. YOUNG, F.G.S.

EXCURSION SECRETARY: MISS E. PEARSE, 3, Bessborough Mansions, Westminster, S.W.

Train leaves Waterloo at 11 a.m., due Clandon 12.16. Meet Miss Pearce in booking office (South Station) not later than 1,45 a.m. Cheap return fare, 2s. 3d.

Walk southward over Tertiary beds through West Clandon village to chalk pit in Guildford Road (No. 281) cut in zone of Marsupites, at junction of Unitacrinus and Marsupites bands; soft white chalk with scattered ITints. Thence to Dean Bottom pit:(No. 282), zone of Micraster cor-anguinum, chalk rather harder with nodular flints in well-marked bands. Ascend the hill. Upper part is covered with thick bed of gravel of doubtful age. The stones are mostly subangular flints embedded in:red and mottled clay, which also contains Lower Greenland chert and some well-rounded Eocene pebbles. Flint pseudomorphs of fossils are abundant. At Newland's Corner, which is at the crest of the escarpment, 562 ft. O.D., there is a splendid view over the Lower Greensand country to the south.

Descend the escarpment to Albury Downs pit (No. 286) at junction of Middle and Lower Chalk; zones exposed are Rhynchonella cavieri and Holaster subglobasus with well-marked band of Actinoclimax planus marl between. Note the high dip of the beds, which contrasts strongly with the gentle dip seen in the previous pits. Cross the very narrow out-crop of Selbornian (Upper Greenland and Gault) and proceed to pit in Folkestone Sands (Lower Greensand). The sand is strongly false-bedded, richly iron stained, and traversed with veins of iron.

Proceed eastward along Pilgrims' Way to brickyard in Gault. Thence to Silent Pool at foot of Chalk escarpment.

Tea will be taken at the caretaker's cottage, 9d. each, with eggs 1s.

After tea ascend the escarpment to Sherborne pit (No. 277), cut in top of zone of Holaster planus. Fossils abundant and easily extracted. Proceed northward, past Scotland Farm, to East Clandon and thence to Clandon Station.

Return train, Clandon, 8.33 p.m., due Waterloo 9.49 p.m.

Walking distance about 7 miles.
