Six land survey plat maps showing townships 11 through 15 south, range 16 east. The U.S. Surveyor General began surveying Kansas after the passage of the Kansas-Nebraska Act of 1854. Plat maps were created at that time to document the surveys. The plats show public lands within the territory divided by range, township and section. Townships were measured in six mile increments starting from the Kansas-Nebraska border. Ranges were numbered in six mile increments east and west from the Sixth Prime Meridian, which crosses through present day Wichita, Kansas. This system is still the basis for legal land description in the state. The Kansas Historical Society acquired a collection of these original plats previously held by the Kansas Secretary of State. The National Archives and the Bureau of Land Management also hold copies of the plats. Kansas land surveyors are the most frequent users of these maps. They use them to verify section corners when surveying land.
