Congrats Larry! It looks like really weathered specimens! The black bar,
if it's the one I am looking at of which you speak, is likely signs of
hydraulics and weathering where the stone is morphing into maghemite??? I
often see this when cutting the Franconia associated with finite cracks not
easily seen. However, I am not sure I am looking at the same thing you are.

I have scales and saws, etc., here if you get in a bind.

> ground more than 3 miles from Todd's find when I found a 120 gram

> I hunted the area between Todd's find and mine for the next 20 + days,

> treasure. Todd was busy and not able to hunt much but on Feb 20 he cam
