In the West, it's called "the checkerboard" – one square mile of public land (640 acres, called a section) then one square mile of private – a direct result of frontier-era policies where the federal government gave away millions of acres of land, some to homesteaders but many to politically connected industries such as the railroads and timber companies. The idea, beyond just enriching a privileged few and scoring political power, was to encourage development of the West – timber for railroad ties and mining supports and lumber mills. The result, in our modern U.S., is a tangle of ownership and, sometimes, an access and land management nightmare. The Crazy Mountains of Montana are one such landscape, a garbled mix of public and private sections, and one where private landowners seem to be playing another old game from the frontier era: blocking access to public lands by controlling sections of private land
