Thanks to Call of the Wild for the following message and photo:

“We were working in the Sychryd this week and have noticed a large number of loose rocks, some of which have fallen and some ready to fall just upstream from the ivy pools / pyranha pools. There is a tree which has fallen but is still attached into the section of rock and any movement to the tree dislodges more rocks. This picture is taken looking back downstream into the two pools with the loose section circled.”
