Grass was free and profits enormous in the cattle business in Wyoming Territory — for a while. The business dates to the 1850s, but the boom came after the Union Pacific Railroad connected Wyoming ranges to eastern markets. For a time it seemed as if every investor got rich. Finally, a weakening market and the overstocked range could not withstand two years of drought followed by a terrible winter. The big boom busted, following an economic pattern repeated many times since in an economy still based heavily on natural resources.
