I thought at first this to be the area, where I was getting some quartz running between the upper and lower yellow circles. The quartz between the circles must have been some lower grade veins or maybe just an abundance of quartz. But now thinking about it more, that may have been on a map NE of another marked location.
I've done some map dowsing for gold prospectors wanting to file a mining claim. Had one guy from Vancouver Island, BC. Over a period of about 3 years, dowsed GE maps zoomed in different amounts at different times, no way to really keep track of what got marked. Every time I'd asked him if the results were consistent with what I'd done in the past.....answer always was yes. Last summer he mailed me 3 of these very large topo maps of the area. When taking out the maps, out popped a crisp new $100 Canadian bill and a $20 just as crip bill on top (a welcome sight). Took my time for 1 1/2 months, but after the fire hazard season was over, he finally got to go to his new mining claim. I have a GE map somewhere with pins on the claim corners.
If you want, can send me the GPS coords (but no hurry) I'll work them in as I get the time. I've been out there in the desert myself already, trying to prospect and live out of my car. Problem is I live too far away and don't have equipment like a drywasher to work the dry desert gravels.
