Nice finds, I would love to see some close ups, allot of the smartphones have macro settings on the cameras just in case you have that? Good work on getting those spots and recoveries!
I know when I was a kid, we spent a lot of time under shade trees in the hottest part of summer. When I am doing a field, I always look for the largest tree bordering it. You just know after following a plow on a hot day, the farmer spent some time resting in shade. Great tip and terrific find. It pays to scan your holes again, doesn't it?
Congrats on your nice coin spill. I also look at the base of trees to see if there has been a lot of fill dirt. Exposed roots are a good sign and can produce some nice goodies as you have already discovered. A three silver day is always good and big silver to boot well, thats just exceptional !!!
