G OODMANHAM DALE is the name of the valley inter- setting the Yorkshire Wolds immediately east of Market Weighton. Though originally of the usual Wood type, evidence was brought forward to show that the upper part of the valley, between Kiplingcotes and Market Weighton, had been subsequently much modified by a reversal of drainage, caused by glacial accumulations in the North Sea.


The evidence that at this time a considerable stream flowed eastwards through this valley into the Vale of York may be summarised as follows :--


(1) The occurrence of a thick deposit of chalk gravel over a large area of the Vale of York, opposite the mouth of the Goodmanham valley ; and the additional fact that this gravel contains a small percentage of erratic pebbles, apparently from the east coast drifts.


(2) That the Holderness drifts on the eastern slopes of the Wolds reach an altitude of between 300 feet and 400 feet O.D., and that the floor of the valley at its highest point does not reach 200 feet O.D.


(3) That the valley cuts through the main watershed of the Wolds, and connects the low ground of Holderness with the Vale of York.


 (4) That west of Kiplingcotes the valley assumes the steep-sided, gorge-like aspect, typical of the overflow valleys in Cleveland and elsewhere, described by Prof. Kendall.
