VI.—Notes on the Geology of Ludlow

Extract

I Have long thought that the vallies of the Onny and the Teme, both above and below Ludlow, had once formed an estuary, and that the promontory on which the town stands had been thrown up by some convulsion blocking up the valley, and turning tha part above the town into a lake, which (by faults or otherwise) eventually caused an opening for the Teme between the Castle and Whitcliffe.
