Join RSPB as they welcome GeoMôn to RSPB South Stack for an interesting delve into the geology and history of Anglesey’s north-western coast. Tracing the links between the geology of the spectacular cliffs at South Stack to Darwin’s theory of evolution, step into a world of geological wonder. Learn all about Cambridge student John Stevens Henslow, who later became Darwin’s mentor at Cambridge and lifelong friend, and his geological insights into the rocks of Anglesey that he studied and sketched over the summer 1821.  Details and booking on their website  https://events.rspb.org.uk/events/142704

Myfanwy – our very own mammoth has been submitted for radiocarbon dating and other studies.  Follow her story here

Discover Anglesey’s world-class geoheritage – a UNESCO global geopark of geological wonders.   Anglesey has such special geology that it is recognised by UNESCO as a “global geopark” – a place where the rocks, fossils, landscapes are world-class. Whether you are a geologist or simply enjoy natural beauty and landscape, Anglesey is one of over 200 Geopark sites in the world and more recently recognised as one of the top 100 geosites in the world!

The name GeoMôn is a combination of ‘Geo’ for all things geological /geographical / environmental and ‘Môn’, the Welsh language name for Anglesey.

Our visitor centre (free to visit) is now closed for the winter but watch out for our list of guided walks?
