SH2026 : Eroding till with erratics

Eroding till with erratics
Eroding till with erratics
Thick deposits of till reach almost to sea level here. Massive, erratic blocks of gabbro are being eroded from the clay-rich material to form an exceptional shoreline, and many more large boulders can be seen in precarious positions on the slope towards Porth Ysgo. While some of the boulders are quite rounded, implying transport for some distance, others are very fresh and angular. It appears that this material was channelled along the western side of Mynydd Rhiw and Mynydd Penarfynydd, from which they are clearly derived as they comprise spectacular gabbros. Once again my patient assistant is posing for scale. An interesting feature here are the remains of timbers still embedded in the ground from the jetty used for loading ships with manganese ore (see SH2126 : View down the final incline towards the now disappeared pier at Nant y Gadwen).
