  It is relatively rare to find Salvia mohavensis in bloom. May 1993, when this photograph was taken, is the only time I've seen the species in bloom at Lobo Point. In 1997, I would find it again at a rhyolite outcrop on the road north out of the valley of Lobo Point.
    I think I stayed this night at Lobo Point.
