a western toad, the shadow is of a tripod leg to give you a size. I saw a Tree frog (there where no trees about) was ready to snap it and the guide tried to lift it but it got away.
this is Mystic lake at San Jacinto, it only appears after rain and we had a lot this year, we got permission to drive down to it, the cottontail bounced through the long grass and sat under the car for shade.
