Ground engineering
The rhyolite rock of the Penmaenbach is both closely-jointed SH7478 : Rhyolite foundations and seriously fractured. The fracturing occurred during the Caledonian mountain-building episode long after the rock had cooled and hardened. Here the fractures and joints intersect to form loosely-bound rectangular blocks. Poor cohesion of the rock mass results in instability, so a large number of ground-anchors have been installed here. The polygonal caps protect the end of the steelwork. The arched adit is one of the tunnels which pass beneath the road to drain water from the railway tunnel through the headland.
