Could you use carefully selected scraps and maps then use colour to make the main route obvious. Could either be subtle or very distinct. Also would allow easy turning off if all the side passages, so an extract of just the main route could be published.<br><br>No idea how hard this is to do in practice.<br>Andrew<br>-- <br>Sent with K-9 Mail<br><br>On 13 June 2021 08:49:44 BST, Tarquin Wilton-Jones via Therion <therion@speleo.sk> wrote:<br>>Hi folks,<br>><br>>I am surveying a cave that could be best described as an insanity of<br>>hidden routes.<br>><br>>When you go through the cave, it feels easy.
