Zoom links for meetings
If you would like to attend one of our online meetings, please email us for the Zoom link.
We meet on the 2nd Wednesday of the month on Zoom (and in person when feasible). Meeting details are sent to members and on request to visitors.

Most Zoom meetings centre on an illustrated talk by an invited guest, some take the form of field reports and some include discussions on topics of interest to our members. All aspects of geology are covered and discussed.

We meet up socially at various locations across our area and enjoy a full programme of field trips further afield to sites of geological interest.

The Rock Show
For many years we have held an annual Rock Show at Uxbridge Central Library displaying rocks, minerals and fossils from our members' own collections. Sadly, the fantastic venue has been lost due to the relocation of the library in 2025.

In 2025 we are holding the Harrow Rock Show at Headstone Manor Museum, free to all, accessible, and open during museum opening hours from 16th September - 4th January 2026.

Local schools can arrange visits to the museum to see the show. We hope to hold several 'hands-on' sessions at which we we show sedimentary, igneous and metamorphic displays, and encourage children to examine them closely.

Enjoy the virtual experience of our Rock Show Online.
