Between 1860 and 1934 the U. S. government kept records of all federal land transactions in Idaho. These records can contain genealogically significant information. Microfilm copies of these records are kept at the NARA Pacific Alaska Region facility in Seattle, Washington.
The records include land transactions under various laws and acts, including: donation land, homesteads, timber and stone, timber culture, desert land, mining, and some cash sales. The records also include tract books (township, range, section, and fraction of section) with lists of owners.
There are records of homestead entries and final certificates, desert land declarations and entries, timber culture entries, abstracts of land sold, and patents delivered.
The records here do not include the land entry case files. Those records are available from the National Archives, in Washington, D. C. Record copies of donation land patents issued are kept by the Bureau of Land Management, and are not included here.
