To answer your question, yes we used detectors, I was with 2 other life long friends of mine. I used an explorer2 and my friends have a Whites Prizm V Detectors. My friend found it and dug it up, he literally threw up when he seen what it was. It was about 5-6 inches under some small gavel and sand on the downstream side of a big rock/boulder. You will defiantly need a quad or some kind of all terrain vehicle to get to that spot. Its a dried up stream in the summer and is wet in the winter, if you look at the google map and zoom out, you can see the way the water flows and where it collects. I figured everything collects at the mouth of a moving body of water, thats the best place to start since the current slows down tremendously at the mouth, letting the gold settle. Plus if you look at the map and zoom out, 3 streams come together right before the mouth, its a prime spot to look for gold. We started at the mouth and detected about 1/2 to 3/4 a mile up the stream before he found it. After he found it we started to hunt more aggressively in the immediate area but only found some small flakes the size of bread crumbs, nothing worth bragging about. My friend has it on display on his mantel over his fireplace so the next time I go over there I will most definitely take pictures of it.
Im going back sometime after summer to look again for a few days, gonna camp out, if your close by or in the area around September hit me up and I will be more then happy to team up and have a look see.
