So I'm putting together a cave map (literally, right now - illustrator is open in the other window) and I've got a question...
The cave has several mud-lined funnels which at certain times of the year are filled with water, but at other times of the year are empty. I suspect they're empty about a third of the year, with varying levels of water throughout the remainder.
The funnels are about 5' deep.
How do I represent them? As dry funnel shaped holes? As pools?
