Ray, these coordinates were derived from Google Earth. Type in Lost Lake, CA and you'll find the road, just south of the Cleghorn / I-15 intersection. Lost Lake is a sag pond located directly on the Fault. I don't know the name of the road, sorry. This was part of my undergrad mapping. The trail is a two-track that connects Lone Pine Road to the Devore area. I'm not aware of any passing restrictions, but it has been 18 years since my last visit.

I have the US Forest Map for San Bernardino Mountains, lists all the forestry roads by number. If you need, I could send it to you.
