The first of 362 land offices was opened at Steubenville, Ohio, on July 2, 1800; the last at Newcastle, Wyoming, on March 1, 1920. The peak year for land offices was 1890, with 123 in operation. The subsequent closing of the public domain gradually reduced the number of land offices, until, in 1933, only 25 offices remained. These functions were gradually merged into other operations of the Bureau of Land Management.National Archives.
