Been reading up on some of this stuff I'm finding, some say they are limaces? and mostly paleo tools? trying to posts yesterdays pics. I've been corn feeding some of these areas and the feral ***s are doing most of the digging and loosing up the soil,..lol up to about 6" deep, helping bring alot of this stuff to the surface. Neat trick. Found a flat sandy area where there is tons of work, about 100 yards below the rocky side of hill, oddly enough where cows used to be penned. Also found a large flat rock, measures about 24"x72" long embeded in ground with what looks like scrapes or etching, will post pics to get some feedback. maybe it nothing or just fissures in the stone.
