[Excursion to] Hayes, Keston, and Upper Valley of the Ravensbourne, July 8th 1916. Owing to the abnormal height of the water level in the valley floor it has saturated the valley gravel and given rise to the bourne. Added note: This pit which is in the direct course of the bourne is now filled with water. From: T W Reader geological photographs 1914, 1916. Geologists&#039; Association Carreck Archive.
