I called the forest service and got some info on the
DUSY ERSHIM
OHV road in the john muir wilderness south of
yosemite.  It turns out the raod is 30 miles + long,
passes by numerous beautiful natural lakes at high
elevation with 9-12,000 ft. peaks around.  The ranger
rated the road as extremely rough, said it is advised
to travel in pairs, said some people take welding
equipment along and said it usually takes 3 days to do
the 30+ miles.
Her Derek, i think you might like this road!

i'll take a look at it.
