pipestone

The eastern Ohio Boy Scout council has an esteemed summer camp award named Pipestone. During the week one has to complete certain ecology, swimming, service and leadership requirements. At the end of the week if one meets the requirements there is a guardedly secret award ceremony in which one receives a stone made of pipestone. There are five years of the program and each year one returns the previous stone and gets a new one with an additional specific carving on it. The five images are a man (native american) holding a stave above his head, a fire, a teepee, a flower and an arrowhead.

Apparently the only pipestone quarry in the country is in Minnesota or Wisconin, can't remember which.
