SNAKE. (also fixed the linky up above)
Yep, that's a snake.
(Sorry - my snake knowledge is rather limited.)
Wow. That is a SNAKE. When I read 'baby-snake', that is not the image that popped into my mind.
Mad PROPS, JZ for keeping your cool.
Wow. Difficult to say - I mean, I googled and apparently gopher snakes use their resemblance to rattlers as a defense.
We need a "What is that snake?" website to answer this sort of question.
Mad props to getting a picture of it!
JZ, I'm leaning towards gopher snake only for the sake of the shape of the head. Rattlesnakes has the more spade-shaped head of a viper and your dad's photo looks more like the elongated shape of the gopher snake.
Checking the ranges on this site reveals most rattlesnakes' ranges are in Southern Cali, rather than up in the Bay area.

Or a "Rate my snake" site.
It was my dad who got the picture. He also got a couple more with a regular camera-camera about half an hour later, when the snake was feeling a little more relaxed and had gone back to stretching out and sunning itself on a nice toasty rock. I know there's one reasonably good picture of the head, which would probably be a lot more useful for ID'ing purposes. I should give him a nudge.
Honestly, I think snakes are pretty awesome, and if it's a gopher snake I want it to go its merry way unmolested. But if it was about to venomously bite my Matilda I want the fucker nuked from orbit.
JZ, is that the position the snake was in when it was rattling? If so, I think it's not a rattler because I *think* the tail has to be pointing up with rattlers.

Though you might want to make sure you have safe search on before googling for one.
