Bob Thrun is correct; you can't argue with the survey tape.
If the tape says the cave is 100 feet long, then the cave is 100 feet long, no matter what the slope of the tape.
Thus a vertical 100-foot-deep, dead-bottomed pit is a cave 100 feet long.
Another example would be holding up a yard stick at many different angles. The yard stick is still one yard long, no matter what angle it is held out.
Thinking horizontal distance for a cave length only confuses the issue. It is best just to mentally delete horizontal length from the entire process. It doesn't count for anything.
And there is an offical document for this. It was described in the January 1981 NSS Bulletin.

Instead of putting "cave" in your title block, just put "surveyed" length (after all isn't implied already that the length refers to the cave?). Same for vertical, just put "surveyed" depth.
To suggest that you have any other information than what you surveyed for horizontal or vertical extent is likely not accurate.
