Photo 9 : On the Big Salmon : Again , the first thing that gains attention is the wave ( red arrow ), the rock is confirmed by the slower water ( blue ), and the rock is upstream of it all and not visible ( green ).
Photo 10 : On the Afon Dyfrdwy . A slow patch of water and the hump of the rock is prominent upstream .

Photo 11 : The rock doesn ’ t show above the surface . The wave and slow patch will tell us where it is .
Photo 12 : Do waves indicate rocks ? Well , not at all . The waves are a result of the river steepening and narrowing . The resulting compression results in a wave train on Berwyn Rapid on the Afon Dyfrdwy . Lots of fun and some good splashes into the canoe . There are no patches of slow water in the wave train so no obstructions / rocks .
