Hmm... this reminds me of the days back in my old house when I would take pictures of the various birds and mammals that went in our back yard. At one time we even had a mother duck and her young come in our yard. We even flooded parts of the yard before we came so they got something to swim in. We were able to see though the months how the young grew into "adult" ducks. And I never had to go to the park.
EDIT: On second thought, I might as well go ahead and lock this thread. This has become terribly off-topic and further tension could be created. I might as well end this now.
@Adam: Most likely, Mammoth itself is a volcano IIRC. Northern California has many volcanic wonders scattered across it, I myself have seen Mt. Shasta and a old lava tube.
