Summary:
The road into and along this geoart is a powerline road. The poles are numbered, and poles #12 and #13 have the best parking (near yy-08). Both also have streams nearby which you can drive up a short ways and park. DO NOT park on the north, or Paiute tribal property side of the road! Do not walk or trespass on Paiute tribal property.
Bring lots of water, stay safe, and cache on.
