now ive got to disagree with the whole "look harder" theory
i have talked to several knappers that live in my area,guys who have been knapping a long time
all of them say the same thing,good luck finding anything local to knapp
maybe southern mn where its closer to other states like iowa,and s. dakota even up near n. dakota maybe find a little here and there
but central minnesota all we have is granite,slate, and crap like that
we have agate,but for the small(i mean smaaaallll) ones you find in our area even guys like jackcrafty and billy would have a hard time to get a point from any of them
any artifacts i have seen that can proven to be found here in ctrl mn looks like material that isnt native to our area
i would realy like to see some knappible material fro this part of the state,and also know what its called and where it could be found
unles some one shows it to me,i have a hard time belieiving theres knappible material here
atleast in any quantity
i ore than likely am wrong,but like i said.ive never found any nor has any knappers i know of in the area
