Collection 2512 - General Land Office Montana Plat Map Collection, 1869-1948

Creator: United States. General Land Office

Provenance Note: Positive photocopies of original Montana township plat maps created by the United States General Land Office were dontated to Montana State University in 2007 by the Tulsa City-County Library, Tulsa, Oklahoma.

Historical Note: In 1812, Congress, with the Act of April 25, 2 Stat. 716, created the General Land Office (GLO) and placed it under the jurisdiction of the Treasury Department. The Land Ordinance of 1785 mandated that surveyors use a rectangular system whereby the land was partitioned into township and range, with 36 parcels per township, each 1 square mile or 640 acres. Each township itself is 6 miles square and based on a series of principal meridians and baselines running across the land. In Montana Territory, Surveyor General Henry D. Washburn's term of office saw the first efforts to survey the land in 1869. These original surveys continued throughout the nineteenth and twentieth century, and many townships were surveyed either partially or in whole more than once as the need arose to show later settlement and land distribution.

Content Description Note: The photocopied township plats in this collection represent two selections of grids in the present day counties of Gallatin, Madison, Broadwater, and Jefferson. The largest group of the plat maps show townships stradling the intersection of the Prime Meridian and baseline, and the second represents a selction of 20 townships located entirely southwest of those intersecting lines. The maps had originally been given numbers which conformed to a state map showing each township numbered from 1 through 2822 for all grids in Montana east of the Prime Meridian, and 2825 through 3753 west of the Prime Meridian. This numbering system is not currently used by the U. S. Interior department online access tool for GLO plat maps and can only be used to identify the desired township by referring to a copy of the state index map. The present arrangment sorts the maps numerically according to township and range number, starting with township 3 north and continuing to township 14 south. The maps in each folder are identified by the original state map numbers followed by the township and range numbers. The number appearing in parentheses separating the sequential state index map and township/range numbers is the number of individual sheets for that particular grid, usually representing the original and subsequent surveys of the township, ranging in dates from 1869 to 1948. Folder 1 also contains a small copy of the state index map.

NEW!: A complete selection of GLO plat surveys is available for browsing on the U.S. Department of the Interior, Bureau of Land Management website. For access click here.
