In the rectangular survey system, which direction do range lines run?
Correct Answer
D) North and south
Why this is correct: The rectangular (government) survey system uses a grid of intersecting lines. Range lines are the north-south lines, spaced six miles apart, running parallel to the principal meridian. They are numbered east and west from that meridian. Why the other choices are wrong: 'Northeast and southwest' describes diagonal lines, not the orthogonal grid of this system. 'They follow natural boundaries' describes metes and bounds descriptions, not the artificial grid of the rectangular survey. 'East and west' describes township lines, not range lines. Exam tip: Remember the mnemonic: T-Rows (Township lines run east-west) and R-uns (Range lines run north-south).
Why This Is the Correct Answer
Range lines run north and south because they are parallel to the principal meridian, which itself runs north and south. These lines are spaced exactly six miles apart and create the vertical boundaries of townships in the rectangular survey grid. Range lines are numbered sequentially east and west from the principal meridian, creating ranges that help identify specific township locations. This north-south orientation is consistent throughout the entire rectangular survey system.
Why the Other Options Are Wrong
Option A: Northeast and southwest
The rectangular survey system uses only perpendicular lines running in cardinal directions (north-south and east-west), not diagonal directions like northeast and southwest.
Option B: They follow natural boundaries
The rectangular survey system specifically creates artificial, geometric boundaries that ignore natural features like rivers, mountains, or other topographical elements.
Option C: East and west
Township lines, not range lines, run east and west. Township lines are parallel to the base line and create the horizontal boundaries of townships.
Range Runs Right
Remember 'Range Runs Right' - if you're facing north, range lines run from your right (east) to your left (west), meaning they go north-south. Also think 'Range = Vertical' like the vertical bars on a ranch fence.
How to use: When you see a question about range lines, immediately think 'Range Runs Right' and visualize yourself facing north with the range lines running vertically in front of you from north to south.
Exam Tip
Draw a quick sketch of the rectangular survey system grid on your scratch paper, labeling range lines as vertical (N-S) and township lines as horizontal (E-W) to avoid confusion.
Common Mistakes to Avoid
- -Confusing range lines with township lines
- -Thinking range lines follow natural boundaries like rivers or ridges
- -Assuming the survey system uses diagonal or irregular line patterns

Analysis
The rectangular survey system (also called the Public Land Survey System) is a standardized method of land description used in most of the United States. This system creates a grid pattern using two sets of perpendicular lines: township lines (running east-west) and range lines (running north-south). The system is anchored by principal meridians (north-south reference lines) and base lines (east-west reference lines). Understanding the directional orientation of these survey lines is fundamental to property description and legal land identification in real estate appraisal.
Background Knowledge
The rectangular survey system was established by the Land Ordinance of 1785 to create a standardized method for surveying and selling public lands in the western territories. This system divides land into townships (6 miles × 6 miles squares) using a grid of township lines and range lines anchored to principal meridians and base lines.
Real-World Application
When appraising rural properties, appraisers frequently encounter legal descriptions using the rectangular survey system, such as 'NE 1/4 of Section 15, Township 2 North, Range 3 East.' Understanding that ranges run north-south helps appraisers locate comparable properties and verify property boundaries on survey maps and plat books.
