The Upper Coquet Valley exposes a section through the Devonian volcanism of the Cheviot Hills. Roadside stops allow us to visit basal Silurian shales, overlain by agglomerate formed during the explosive phase at the start of the igneous activity. Rhyolite lavas are then followed by large volumes of Andesite and ash. In places, glassy andesite is cut by veins of jasper and occasionally agates may be found.
The Acklington Dyke (Palaeogene)is visible in the bank of the river at one point.
Essential equipment:
Sturdy footwear, outdoor clothing, lunch. Path is over rough ground in places although most localities are close to the road.
