Talks
We normally meet on the 2nd Thursday of the month at Oaklands College in St Albans. The talks are on a wide range of Earth Science topics, given by people who are experts in their field.
During COVID-19 restrictions we held our meetings over Zoom. Now restrictions have been removed we have resumed face to face meetings, using Zoom during the winter months.
Please check our Calendar for full details of our exciting 2024 programme of talks.
