Ramtag - Well ranches like Deseret, well not nearly as big, but ranches have sold in the past. Typically they go for between $70 - $200 per acre. Yes that is a per acre figure.
But you take the 500,000 rough acres that Deseret makes up and at the low end that would be $35,000,000 and high end and it would be $100,000,000.
Not too many buyers on the market who could write that check, and a bank would not be likely to finance, unless you could find a gold mine, or huge oil deposit under neath it.
