About the Historical Index


The Historical Index (HI) is a chronological listing of all actions that affect the use of title to public land and resources for each township.  Applications are noted to the Historical Index only when they segregate the land.

It is a ledger-type document that consists of notations that elaborate on the information shown on the Master Title Plat (MTP).

There is a Historical Index for each MTP.  The heading of the Index is identical to the heading of the MTP.

The Historical Index consists of a series of columns for entering land status information for the township.

Beginning with the left hand column:

SECTION or TRACT - The first column lists the section(s) or tract number(s) involved in a case.  When a case involves multiple sections, each section number is listed on a separate line in numeric sequence.

SUBDIVISION - The next column is titled subdivision.  It is broken into three sub-parts: aliquot parts, lots and other descriptions.

  • Aliquot parts are shown with an X in the column.  Each X indicates a quarter-quarter, or 40 acres of a section and its location in the section.

    LOTS is for denoting, by number, the lots within the section in the case.

    OTHER DESCRIPTION may contain the following information:
  • See remarks
  • Land descriptions, which do not fit, into aliquot parts or the lots column.
  • A key township or other township citation.
  • The word ALL-referring to the section notation.

ACRES - The acres column is for acreage of the case for the township.

KIND OF ENTRY OR PURPOSE OF ORDER - The column for Kind of Entry or Purpose of Order explains the action that was taken.  Abbreviations without periods are used whenever possible in the column. This column contains information about the type of document filed.  For example, such abbreviations in the column may include:

  • HE Pat    Homestead Entry Patent
  • CE Pat    Cash Entry Patent
  • OG Lse   Oil and Gas Lease
  • PX Apln  Private Exchange Application

SERIAL OR FILE NUMBER - This column contains the patent number on title transfers from the U.S., warranty deed identifications and reconveyed lands.  It also shows the order numbering when they are numbered.

DATE OF ACTION - The next column shows the date of action in chronological order.  This date is when the document was signed.  When the order or document is not numbered then the date is used as the document identification.  If two or more entries have the same date, enter them in document number order.

REMARKS - The last column titled remarks contains miscellaneous information about the case.  Notations of closing, terminations and rejections of the case will be cited here.  Also, information that was too extensive to be entered in other columns such as -- metes and bounds descriptions, lengthy aliquot parts descriptions, segregations and other land descriptions when the "other descriptions" column contains the notation "see remarks." The serial number of the case may also appear in this column.

Some other things about the Historical Index:

The Historical Index data is read from the back (latest) to the front (earliest) and from the bottom of the page (latest) to the top of the page (earliest).

There is a separate Historical Index for actions, which affect the acquisition, uses or disposition of acquired lands.  The addition of the words "Acquired Lands" is added to the heading for this Index.

Mineral Location and Contest Index is an index sheet that uses the same format as the Historical Index but is used to record mining claim litigation and contest actions.
