Who Owns the West?

Found on digg.com, this map was posted on strangemaps.com.  The portion of each state shows the amount of land in each state owned by the Federal Government, but not the specific location.  It's centered in each state just to show the relative size.

This map appeared as an illustration to ‘Can the West Lead Us To A Better Place?‘, an article in Stanford Magazine, a periodical for and about alumni from that university.
