Description:Excerpt from Memoirs of the Geological Survey: England and Wales, the Geology of Eskdale, Rosedale, &C The following Memoir describes the geology of the highest and most picturesque part of the great tableland of the north-east of Yorkshire. The Map to which it refers shows that this region may be regarded as a vast model exemplifying, in a striking manner, the relations of topographical feature to the nature and disposition of the rocks underneath. The strata being nearly horizontal and little disturbed by dislocations, the valleys radiating from the tableland can be traced out as the results of erosion, with a precision and completeness unattainable in other districts of the country where the geological structure is less simple. Standing at the head of any one of these valleys, the observer has the whole sequence of rocks laid bare before him from the middle of the Lower Oolites down to the Lower Lias, and with his eye can follow the successive subdivisions of the Lias as their outcrops wind along the slopes. The absence of Drift over most of the country depicted on the Map is one of the most remarkable features of the geology. Boulder Clay, of the usual type, extents to a height of about 800 feet up the valleys that trench the northern front of the tableland, but is not met with in the interior, nor has any trace been found there of local glaciation. These uplands appear to have formed an insular space round which the ice-sheets swept but which remained unsubmerged. In the Drift edition of the Map the limits of the glaciated and non-glaciated tracts can best be seen. The Lias and Lower and Middle Oolites are well represented in the District, and the present Memoir is mainly devoted to a description of these strata as developed within the area embraced by the Map.
