Which lines run parallel to the principal Meridian and are six miles apart?

The correct answer is that the lines running parallel to the principal Meridian and spaced six miles apart are known as range lines. In the Public Land Survey System (PLSS), range lines are essential for dividing land into townships and defining property boundaries. They run north and south and create a grid that helps interpret land locations based on their relationship to the principal Meridian.

In the context of land surveying, meridian lines reference the central vertical lines used for measurements, but they do not describe the parallel lines themselves. Latitude lines, on the other hand, run east and west and describe horizontal positioning rather than the vertical ranges pertinent to the question. Boundary lines, while related to property definitions, refer generally to the edges of parcels and do not specifically reference the systematic six-mile spacing characteristic of range lines.

Understanding the PLSS framework is vital for code enforcement and land management to identify and manage land properties effectively.
