Bringing this back from the dead. I took the pdf from the above link, georeferenced it and created a GPS map for Avenza Maps. I and a few others tested it this weekend while at Harlan. While it is not EXACTLY perfect. It's pretty damn close. To where I never felt even remotely lost on my first trip there as a driver and was able to find my entire group on the first shot whenever we got there. If anyone would like it, I can email them the file. It's free. But beer money, donations, or a new oil pan(thank you Lions Den) are accepted....No handy's.....Here is a PDF map of Black Mountain.
It is not georeferenced, (expensive program!! ) But, you can upload it to your phone and the PDFMap app reads it.
I tried to upload it here, but it seems it is too large?!
Here is a link to it...
