II. Lower Eskdale
Published online by Cambridge University Press: 01 May 2009
The outcrop of Dogger described in this paper covers an area 12 miles in length, stretching S.S.W. from Whitby up the lower course of the River Esk and its tributary valleys of Iburndale, the Murk Esk Valley, Egton Grange, and Glaisdale. Unlike the coast natural exposures are few and unsatisfactory and in Lower Eskdale in particular are only encountered where becks from the surrounding moors cut through the massive boulder clay plug which partly fills the main valley. Other exposures occur in abandoned alum works, disused ironstone adits and small quarries. The outcrops cross diametrically a part of the Whitby Basin, the Eskdale Dome, the Goathland Syncline, notch the main Cleveland Dome (Lees and Cox, 1937),1 and range in height from 35 to 500 feet O.D..
