V. Notes on Charnwood forest
Published online by Cambridge University Press: 01 May 2009
Extract
In the midst of a comparatively tame and highly cultivated plain of New Red Sandstone near the centre of England, there rises up a part of the under crust of the earth which presents so much the appearance of an island as to lead the imagination at once to those remote ages when its porphyritic Peaks and Syenitic Knolls were surrounded by the sea. The geological history of this celebrated spot has been skilfully unravelled by Professors Sedgwick and Jukes (Article in Potters's Charnwood Forest); the Rev. W. H. Coleman (Article in White'Directory); Mr. Edward Hull (Memoirs of Geol. Survey); and others.
