How are ranges defined in the Alberta land measurement system?

In the Alberta land measurement system, ranges are established as lines of longitude that are measured every six miles. This is part of the rectangular survey system used in many regions of North America, which organizes land into a grid of townships and ranges. Each range is a vertical column of townships aligned north-south, with each range separated from the next by six miles. This systematic division facilitates land surveying and development by creating a clear and consistent method of defining property boundaries and locations.

The emphasis on using lines of longitude rather than latitude is important, as it reflects the orientation of the surveying system. Lines of latitude, which run horizontally, are not employed for ranges. Instead, they are utilized for delineating township boundaries, which are measured every six miles north-south, creating a grid-like structure that is essential for land identification and management in Alberta.
