This evening I was hiking with my mother (in Southern California - Orange County) and came upon a rattlesnake coiled at the edge of the path. When I say "came upon", I mean "nearly stepped on." 
It was a rich, orangey-red color, I'd estimate about 4 feet long, and had a strikingly flat head. Absolutely beautiful! The light was dim, so I can't be sure of the markings, but it didn't seem to have a very bold or prominent pattern. My mother, who was closer than I to it, said that it didn't have the black and white rings at the base of the rattle that we've seen on Western Diamondbacks.
What type of rattlesnake do you think it was?
Thanks
