Monday 9th May, 2:00 pm to 5:00pm. The walk is run as part of the Northumberland Coast AONB series of geo-diversity walks.

Walk summary: “Stuff your eyes with wonder, he said, live as if you'd drop dead in ten seconds. See the world. It's more fantastic than any dream made or paid for in factories.” (Ray Bradbury, Fahrenheit 451)

The temperature at which the Whin Sill was injected between the kilometre thick layers of Carboniferous sedimentary rock was over double that at which paper will combust, the Fahrenheit 451 of Ray Bradbury's dystopian novel. At over 1000 degrees Celsius the Whin Sill magma would have glowed a bright yellow, painful to the eyes, albeit this would have been impossible to do as the molten rock remained trapped a kilometre or so underground. 

This walk explores the rocks on this beautiful part of the coast which give the evidence for this story, showing what happens when hot magma and cold rock meet. The walk will also also help to explain the story of how the 300 million year old roots of Bamburgh Castle came to provide such a nicely defensible landform.

Do I need to book? This event has to be booked in advance. The walk costs £10 for each adult (children free). The walk will be limted to 20 people. To book a place on this walk please This email address is being protected from spambots.

    A sharp eyed walk along the beach at Cocklawburn or on Lindisfarne and with a bit of luck you may find a small disc, shaped like a tiny petrified polo mint.

    Where has Hadrian’s Wall Gone?

    Before I answer that question, here is a little bit of background information from a manuscript fragment recently discovered in an obscure roman outpost at Ecclesia Novum-Oppidum near to the Fluvium Collegium (surprisingly close to where I live!) and published in the journal Falsus Nuntium.

    Northumberland Coast Rocks!

    This project, which was completed during 2015 organised by the Howick Heritage Group and supported with HLF funding, delivered a book, some educational work with a local first and middle school and a series of walks and talks. In this section of geo-diversity resources you can have a look at the presentation given for the walks and talks as well as much of the material which was used in the educational work including lesson plans, activities and exercises.  There is also a handy guide to fossils to be found on the beach at Seahouses (and elsewhere on the coast).


  • "Ian is an ethusiastic geologist and if you go on enough of his walks you soon will be too! Although I have visited the Northumberland Coast many times before, learning about its geology allowed me to see it from a very different perspective. Ian was an enagaging and entertaining guide and as a result of his walk I was able to understand more about this fascinating area."
