I am adding to this post.
My friend jim is now doing time for picking up arrowheads. His assessed fine was $2,600.00, since he is a poor man and unemployed, he was sentenced to time in prison. His buddy was able to pay his fines, and was not incarcerated, however, now he has a police record for theft and trespassing.
This link provides wouldbe arrowhead hunters with advice and warnings.
