not to be a stickler for semantics but I think a lot of people are improperly referring to the roads around Mt. Hamilton as all being Mines Rd. I've prepared this handy graphic (with the help of the Alpine Speed Stars map too) to help you out.
The road between the Lick Observatory and The Junction is San Antonio Valley Rd, and I think not too many people realize that. It is not Mines Rd, but is part of Hwy 130 (which then continues on Del Puerto Cyn Rd out to I-5/I-580).
I believe right now it is San Antonio Valley Rd which is the most gravelly portion. The other roads are relatively clearer and still drivable. Which is a damn shame because that section coming down from the observatory to the Junction, used to be one of my favorite driving roads.
