This full-day trip celebrates 100 years since the Geologists’ Association Excursion on 19th May 1917 and will attempt to re-enact the route as closely as possible and to deliberate on the origin of the gravels as on the original trip. The 1917 trip began at Norbiton Station and finished at the Windmill on Putney Heath. It was an afternoon trip with a suitable stop for tea, as was the custom; we will begin in the morning and find a suitable watering hole for lunch. Details to follow.

Cost & booking: There will be no charge for this trip but it is essential to book your place with Sarah Stafford at the Geologists’ Association –
