Description:
While conducting elementary field-classes in the Ingleton area it is not possible to show students any convincing grounds for separating the Ingletonian Series from the Coniston Limestone above. The field-evidence which so strongly impressed Hughes, Goodchild, Gunn, and Green, and which apparently convinced Aveline against his will, still exists. In all three streams the highest beds of the Ingletonian are slates, which might be thought to show a gradation into the Coniston Limestone above, and the dip and strike of the Coniston Limestone appear closely similar to that of the near-by Ingletonian. Against these tangible facts arguments based on petrological similarities, even the evidence of the Neptunian dyke, are apt to seem slightly strained. Accordingly, during a field-excursion I suggested that an attempt be made to excavate the actual junction, and during the summer three students of Imperial College, Messrs. R. W. D. Elwell, G. J. H. McCall, and A. F. Trendall, have succeeded in laying it bare. To their enthusiasm and hard work the success of the attempt is wholly due. Owing to the kindness of Mr. W. S. Worthington, of Ingleton, the new exposure will be left open indefinitely.
