This should be a fast find but the coordinates may not be trustworthy. The GPS readings seemed to bounce around. The clue should get you to the cache quickly.
The logging road is fairly rough. At the time of the hide two small cars were able to safely climb to the switchback near the hide. Parking lower down on the pavement is an option as the hide isn't too far up the dirt road.
Access from the highway is via Kane Road right beside Sitkum Creek or Granger Road and then Alpine Road a bit further East on the highway.
