Federal surveys imposed a rectangular grid that shaped American settlement

Evidence

Federal law determined the very shape of the land. Measuring and surveying were essential. Men with sextants, chains, pegs, and axes worked to turn the land into convenient squares, small squares and big squares, but, in any event, squares that could be described exactly, whose location could be pinpointed; squares which then could be auctioned off to buyers. … And the lots and farms in the West were determined by the merciless, invisible grids that the government and its surveyors stretched over the land. The law of 1796, and its later versions, turned us into a nation of squares. — Lawrence M. Friedman, A History of American Law, 1394
