As of 11/17/2012, there are Forest Service signs on most of the dirt roads in this area. There was even a small sign off Highway 338 that reads "Nye Cyn". The dirt road is still well graded initially and marked as road 42031. To continue up the canyon you switch to road 22510 about half way in. From the intersection of Highway 829 (South of Wellington, NV) and Highway 338 it's 12.8 miles South to the Nye Canyon road.
"After the first glass, you see things as you wish they were. After the second, you see things as they are not. Finally, you see things as they really are, which is the most horrible thing in the world."
