As of 2/24/13, the dirt road that leads to the DPS 4WD parking spot has been graded and is passable by almost any passenger car. It appears that the road was improved in order to replace the power poles that the road follows.
Thank you for this update. I'm sure it was a nice surprise to get there and see a lovely road rather than the rut-fest that had been there. I'll update the page momentarily.
As of 1/16/2014, there are a few washouts on the road -- no problem for a vehicle with high clearance and big tires. One had been filled partly with rocks, by helpful motorists-- a traveler on that road may wish to stop before the worst washout, and add some rocks to the pit before driving across.
