[Therion] Surveying Maze Caves

[Jonathan Prouty]

Hello all,
I have a question regarding surveying (and mapping) extremely mazy
multi-level caves. There is a cave near my home that has never been
mapped, I assume due to it's extremely mazy nature.

I am considering taking it on as a project, however, I have no idea how
to survey it. Do any of you have advice as to how to best manage such a
survey?

I imagine I will have to be extremely careful with how I create scraps
in therion, as well. I can think of several places in the cave that
have 5 or 6 passages all meeting in one small room.

Any advice would be greatly appreciated. Thanks :-).

Sincerely,
Jonny Prouty
