Our research note for December reviews the public land survey plat maps of Minnesota, available on-line. Minnesota was the 6th state developed from the Old Northwest Territory*, and the plats on this site include those drawn by the original surveyors from 1848-1907, as the land was opened for settlement. The images can be downloaded, but be warned that the files are large as the maps include many details. There are two versions for each of the 3,500 maps in the collection. One is high resolution and the other is a sampled, lower resolution image. The note itself can be found at http://www.parkbooks.com/Html/res_gis.html Others in our monthly series can be found at http://www.parkbooks.com/Html/research.html Enjoy! Mary *The others were Ohio, Indiana, Illinois, Michigan and Wisconsin! Mary Bakeman [email protected] Park Genealogical Books http://www.parkbooks.com/
