Which section of land is not typically part of a township's organization?

A township in the United States is typically divided into a grid of sections, which are outlined by a numbering system. Each township consists of 36 sections, each typically one square mile, arranged in a specific manner. The organization of these sections follows a predictable layout from one to thirty-six across a six-by-six grid.

The correct choice, which indicates "Diagonal section," is accurate because there is no section referred to as a diagonal in the standard layout of townships. Townships are divided into north, south, and central sections based on their relative position within the grid, but a diagonal section does not fit into the conventional naming system used for section division.

Thus, the term "diagonal section" lacks recognition in the traditional organization of townships, solidifying it as the option that does not conform to a township's structural framework. The other choices represent valid divisions within the conventional structure, although they are not terminologies officially recognized in legal descriptions or surveying practices.
