How America got laid (out - that is)
Interesting piece of how America got divided up and the different ideas on how to do it -
"Though its taken for granted today, the systematic division of land in the United States still defines the countrys geographical fate. In its early stages, the survey pit Thomas Jefferson and Alexander Hamilton against one another, with their competing visions of who should own and profit from Americas land, and it enabled Americas great land grab from the native people of the continents Western reaches. More than 230 years later, the same system still governs distributions of mineral rights on public lands and underlies digital mapping systems. If you know what to look for, you can still find its legacy in the physical markers that dot the land today, in the neat divisions of the Western states, and particularly in Ohio, where a not-yet-perfected survey system created messy, irregular divisions that still hash the state.
