Please note change of start time to 10.30am.

We will visit exposures to see a variety of sedimentary Devonian, Carboniferous and Triassic rocks, see trace fossils, palaeosol, marine crinoids and corals, plant fossils and no less than two unconformities. We will examine and discuss folding and faulting structures that exemplify the uplifting processes that build a mountain chain and that opened up an ocean.

We will start at the Windmill Inn, at 10:30, when the tide has fallen sufficiently, and end at 16:30 at the steps from the beach near the Royal Inn and the lifeboat station, when the tide will be rising again. The total round-trip walking distance is about 5 km. We will take a lunch break from 12:30 to 14:00, which will be a good opportunity for a picnic at Portishead Lake Grounds. Bring binoculars for incidental bird watching.

I have already sent details including itinerary, graphics and a Risk Assessment to some responders, but if you want to come, or you haven’t received these details, please contact me by filling in the form below. We also invite members from the South Wales Geologists’ Association, the Bath Geological Society and the West of England Geologists’ Association.
