This was our 4th different icon today (aiming to do 11). We did this one while we were doing the Wherigo. Its a really interesting area - we spent about an hour here but I really I wish we could've stayed longer.
The three benches in a circle are now down to two sadly (it looks like somebody has uprooted one and used it to start a fire at the other end of the quarry).
I took some pictures (which I'm posting) and answered the questions (which I've emailed).
