Ha ha, what do you think mud is made of? Clay? And a bit of water, but then most things on earth have a little water, so just stick with clay. Have a look at my interpretation https://therion.speleo.sk/wiki/drawingchecklist Search for mud on that page.

So, Still a therion noob despite having put all my data over. Finally working on cave maps not just line plots, thanks to a caving buddy who is leading the charge. So this seems strange but.... why is there no mud area symbol? I am sure someone else has already addressed this. I cant be the only person to survey in a muddy cave. Surprised really, my floor detail is usually sand, cobbles, mud, water or breakdown. I've never really had to use clay or debris. Can someone help put the mud into my cave maps? It seems like such a common and important floor area, can someone with the expertise make it so that mud just comes up on the drop down area list in map editor? Rob Countess
