Thank you yatsek. I did include a link for the mojave green rattlesnake and I'll look for a good pic of the protected desert tortoise that is in the Woodbury area. I didn't personally see any animals during my visit although I did see deer tracks on the road.
You now need to park near the sign that says "Dead End" because the road is gone. It'd be tough for even an ATV to go up it and would be best on a dirt bike now. Figure 6 miles and 2500 elevation gain.
