I bought a device to map a set of caves, but I don't really know how it works. I pressed a button at a few spots in some of the caves, and it just printed out this gibberish:

Square grid?

I'm sure you'll be able to interpret this data to map out the caves we visited.
(And find a hidden word in the process!)

Excellent question.

On a 27-by-5 grid, draw arrows in the indicated directions from the indicated points (2 units south and 2 units east from the point (1,1), 1 unit east and 1 unit west from the point (2,3), and so on). The lines thus drawn spell out letters.

Here's a (not very good) picture to demonstrate the solution:

map

The letters appearing are

S, P, E, L, U, ~n, ~K

giving the word

SPELUNK.

  • $\begingroup$ @IanMacDonald Thanks for editing! There was a mistake in the OP originally, and once it was fixed I corrected my picture but forgot to change "west" to "east" in the first spoilertag. $\endgroup$
