Wednesday 8th September, 10:00 am to 1:00pm. The walk is run as part of the Northumberland Coast AONB series of geo-diversity walks.
Walk summary: The massive forces unleashed as the earth's continental crust moves around driven by mantle convection are made all too obvious when events such as the Nepal earthquake or that around Amatrice in central Italy happen. These forces do seem rather distant on the geologically quiet and beautiful coast around Howick with not even the smallest earth tremor to disturb the butterflies feeding on the sea campion. The evidence in the cliff face here at Howick tells a different story though, with massive slabs of rock moving many tens of meters and igneous rock being injected into the cracks between them. Signs that in the Carboniferous period some 300 million years ago that the Northumberland coast was in closer proximity to continents colliding.
This walk will explore the sequence of sedimentary and igneous rock which make up this beautiful coastline and paint a picture of what was going on here about 300 million years ago.
Where do we meet? We meet at the parking spot on the bend by Sea Houses Farm just south of Howick. Grid refrerence NU258173. Please can participants gather, socially distanced, unless in support/family groups).
How long is the walk? This walk will be approximately 5 km and will involve some scrambling across rocks on the foreshore. Strong boots are recommended and some may find walking poles helpful.
What else do I need to know? Full details will be sent out on email to everyone who books. This will include what to bring and how covid guidance will be followed.
