Which legal description method is regulated by the U.S. Department of the Interior's Bureau of Land Management?

The method regulated by the U.S. Department of the Interior's Bureau of Land Management is the rectangular government survey system. This system is primarily used for land description in the United States, particularly for large parcels of land and those located in rural areas.

The system divides land into a series of townships, which are further divided into sections. Each township is typically six miles square and contains 36 sections, each one mile square. The rectangular government survey is beneficial for its standardization and ease of mapping, making it easier for landowners and government entities to identify and communicate land boundaries.

This method is essential in areas where metes and bounds descriptions may be impractical due to the scale of the land. Unlike other methods such as metes and bounds, or lot and block, which are based on specific landmarks or existing subdivisions, the rectangular government survey provides a uniform framework that can be used across various states and regions. This is why it falls under the jurisdiction of the Bureau of Land Management, which oversees public lands and resources in the United States.
