As I was making my way up the trail to the top of Mt. Davidson, I found a large boulder with splotches of lichen growing on it, and two perfect Eucalyptus leaves, one on each side! I didn't place either leaf, this is photographed as I found the leaf, and I didn't even clean up the area! (The other leaf picture will be uploaded tomorrow.)

This image was taken during my trip to San Francisco during September 12-15, 2011.
