Got my 35ft motorhome to the entrance of Lost Treasure Mine no problem. Also on Harquahala Mine Rd, either from Salome or I10. There are GPAA Claims there, but there are also other claim markers within the GPAA boundries. I talked to Kevin Hoagland about them and he said ignore them, the GPAA coordinates are soild.
There are shafts and addits everywhere and most are fenced off. I did go into some of the addits but stayed clear of shafts. Jeff Williams suggested detecting just east of the Cemetery, but there is so much trash, you might want to try a small coil. I found no gold searching 3-4 days, cool area though.
