A collection of state geological maps using the same underlying database structure. PLSS townships are subdivided in a spatial hierarchy of first, second, and third division. A boundary of an area designation within which National Forest System land parcels have management or use limits placed on them by legal authority above the Agency level (e.g. The Library did not produce it for, nor is it suitable for legal, engineering, or surveying purposes. Geochemical analysis of sediment samples from the National Geochemical Database. PLSS surveys, which are available for portions of land in 30 southern and western states, are made by the Bureau of Land Management (BLM). The U.S. Public Land Survey System (PLSS) was established shortly after the Revolutionary War as a way to describe and record parcels of land for legal purposes. In this system, land is divided into pieces called townships that are generally 6 miles on a side and contain 36 sections.
