I came upon this 4x4 road after going off trail some distance up hill. This road turned out to be a continuation of FR402D past the end point shown on the map. I continued to follow this 4x4 road and was surprised that it lead over the top of Peak 9850, the highest point on Burro Mountain, then down the north side right to where I had car camped on 7/13/2016. At that point I turned around and headed back to my camp on FR402D.
