The well-known section alongside the Great Northern Railway just north of Sandy Station shows a total thickness of about 50 feet of ferruginous sands with occasional concretionary ironstone bands, resting on the Oxford Clay. This is therefore the lowest portion of the Lower Greensand. Numerous specimens from different levels in the exposure have been collected and examined, but they were all found to be very similar, and as a matter of fact not very interesting, so that a short description will suffice.
