Section lines

From Wikipedia, the free encyclopedia

Section lines in the United States are one mile apart. When surveyors originally map an area, for instance a township, it was their custom to divide the new township into 36 - 1 square mile sections. Property ownership often followed this layout. A section is a 1 by 1 mile area. A half section is 1/2 by 1 mile area. It is proper to continue this division down to a 1/4 - 1/4 section which 1/16 of a section, or 40 acres. The next division getting smaller is 10 acres, and then 2.5 acres. Besides property ownership, roads often followed the section lines, and one can often still see them in modern maps, even in urban areas. In rural areas, these roads are called section roads, and often exist primarily so that farmers can access their land.
