The part of the river Wharfe where I took the photographs was at the middle course. I knew this because the river was wider and deeper (there has been a few accidents in the past where people have almost drowned). The surrounding valley is wide and much flatter than in the upper course. There are also a lot of meanders in the middle course and next to where I was there was a small beach which is found on the inside of a meander bend.

The load I collected here was class 4 - sub rounded and some class 5 - rounded.
