The best thing about 9 Mile Canyon is that it's 40 miles long.
You should be able to loop back through Whitmore Park, Minnie
Maud Creek, or Argyle Road. The road is level dirt.
If you pick a good spot, and have time to explore, you may
find petroglyphs, pictograph, pithouse dwellings, and other
ruins from the Fremont Indians. I was half-asleep the whole
way back, so I missed a lot.
