Waterfall. Count up three levels of rock from the pool and you can just barely see Susan standing in the dark under the overhang.
Josie after eating some orange mushrooms.
Billy Bob having a li'l drinkie.
Columbine (they grow here).
(Most of these taken by the D-a-W.)
Update: If you still haven't spotted Susan at the waterfall, it's probably because she's not there, and the waterfall is actually only about three feet high.
