Misidentifiaction: If you are looking at the plant, not likely to be missed, but if you only have a twig, bummer. Determine it is a Cupressus, most have more or less rounded stems and most have the branchlets radiating out in all directions rather than flattened sprays. I did say most.
If its blue its the Arizona cypress, if the cones are larger than an inch it is likely the Monterey cypress, if its green, no cones and no plant to look at, punt.
Location: There is a nice planting at the corner of Alturas Way and Cabrillo College Drive on the north side of Park.
At the now closed Mt Madonna Inn at the top of Hecker Pass.
