I should have brought the camera, because on the 3-and-a-bit mile loop out past the falls to Goat Rock and back, brooksmoses and I saw many different sorts of very nifty wildflowers, a whole flock of butterflies, several different species of lizards, and assorted cool rocks and views. Also, on the way out of the parking lot, we saw a coyote crossing the road.
Goat Rock is neat. It's a very large chunk of stone on the edge of a cliff, and one end of it is hollow. If you climb over the ridge down the back, you can get into the bubble on one side, then stick your head out over a very long drop indeed. Much fun. :)
