Master Title Plats are the foundation of our land records.  It's a drawing of the most recent survey or protraction (unsurveyed lands) by township.  It's a graphic plat illustrating current federal ownership, agency jurisdiction, and rights reserved to the Federal government on private land within a township.  Master Title Plats also known as MTPs or plat maps, are continually updated as status or survey information changes.  There are also supplemental plats to enlarge an area with a lot of detail, and there are mineral plats for certain uses such as oil and gas leasing, sodium leasing and other types of minerals such as geothermal etc.  Also available are Historical Indexes (commonly known as HIs).  The HIs accompany the Master Title Plat and they capture the history of the particular MTP, and current information on the plat.
