Section line refers to which of the following features?

• A. A line at the extremity of a section boundary
• B. A line marking a river boundary
• C. A line across a township
• D. A contour line

Answer: (A)

A section line is the boundary line that surrounds each section in land surveying. In the Public Land Survey System, a township is subdivided into 36 one-square-mile sections, and the lines that lie at the edges of a section—separating it from neighboring sections—are the section lines. They form the grid within the township and connect section corners, defining precisely where one parcel ends and another begins. This is different from lines that mark river boundaries or township-wide framework; contour lines, meanwhile, show elevation, not political or land-describing boundaries.
