Thanks Steve. From what I can tell, it is the same. Also, I found some info that it can be found in limestone outcroppings, either in the prairies or along creeks and road cuts. The stuff I bought has been heat treated and looks to me like smoked pork (segue to food discussion now) with its gray and pink tints. The raw stuff is described as "butterscotch" (again a food reference). This should be interesting. I'll post pic's if I find some.
