I would like to connect with petroglyph hunters in the Phoenix Metro area to help me search out some little known/hard to get to petroglyphs in the surrounding area. I do a lot of research, sometimes a recon trip to check out access to the locations and then hike in the early AM on weekends to find them. 
As you know most of the hiking is off trail and involves serious rock hopping. Experienced desert hiking, researching and navigation skills are a big plus.
I have a large collection of site location info and all the BLM maps for most of the state. Lets combine resources and see what we can find.
So, if you are interested in the search contact me via email.
Thanks, Dave
