On a visit to Notts II today we found several places of deliberate muddying of formations. Why do cavers grab hold of formations with their muddy paws when there is a perfectly obvious taped route round them. I makes my blood boil!
We got most of it off with water but it needs some delicate nail brush work before they get engrained permanately.
