thanks
hawk dancer the gravel was already broke when I picked it up, and it is a river rock I guess you could say.
It is quarried out of ancient river beds to the west of here and way above the current river levels.
Glis Glis, I could make a vid I guess.
I know someone who has a one, he videoed me making something at the SW LA knap in this past November. It went real good and turned out nice and only took fifteen minutes.
I'll see if I can get a copy of that.
