SH3741 : The Erch valley above and below the elbow of capture
taken 16 years ago, near to Llwyndyrys, Gwynedd, Wales
The Erch valley above and below the elbow of capture
The sharp, elbow-like, bend in the river (on the very right of the photo) is evidence of river capture. This is where a stream has eroded backwards into the catchment area of another and has beheaded it. Carnguwch church can be seen on the left, while Penfras-uchaf is the farm on the opposite side of the valley.
