Observations by alw46

This snake should not be in this region, but it looks too much like the Arizona black rattlesnake to be anything else. This one was killed by a neighbor in their yard. I saw one a week or so before that while hiking in Cow Mountain on the East side of the Ukiah Valley. I was unable to get a photograph before it moved away.
While this picture is not very sharp, the one I saw the hind 24 inches (the rest was obscured by the brush) was very shiny jet black with the narrow white bands and a fair number of rattles.
