Trap Door with Puzzle Totems near Whiterun

[Mr. J.D. Gumby]

Just found a trap door/puzzle totem (Snake, Eagle, Whale) with a handle out in the middle of Whiterun's territory, almost directly northwest of the North Brittleshin Pass and southeast of the giant camp on the plains.

Anyone got an idea of the combination for this one? There's a yummy-looking chest down there. :P

The combination is there somewhere. It always is.

Bah. Spoted the signs just now - they were virtually invisible in the dark... Only one sign for it, though, but that allowed the options to be cut down to a reasonable number. :P [Whale / Eagle / Snake]

All three are there, but two have fallen off.
