This was another throwback road I did recently on Surewhynotnow from Panamint Valley in Inyo County:

Interestingly Trona-Wildrose Road was being reconstructed when I passed through. Traffic was directed onto mildly grades dirt shoulders and not the actual roadway. I want to say Wildrose Road was closed which if I recall correctly is the way I wanted to cross eastward to reach Towne Pass over CA 190.
