Burlington ballast

["Robert Sorensen" <rksmes@e...>]

A while back there was a note regarding having "CB&Q ballast" available for 
sale at the coming meet. My question for today is what exactly made it "CB&Q 
ballast"? Was it color, unique because of source or something else?
I know that in Minnesota and westward, the NP and GN used crushed granite from 
around St. Cloud, MN. So, did the Q use the same ballast down towards LaCrosse?
Thanks for someone who will answer.
