A Slope County township map answers two different questions around Amidon: which local township a property sits in, and where it falls on the survey grid. This guide covers the free Slope County, ND options and how to read them.
Civil townships vs. survey townships
Where civil townships exist in the county, they are named local units, and their duties near Marmarth depend on North Dakota law. The survey township cited in deeds near Amidon comes from the Public Land Survey System, in which each township is about 36 square miles, divided into 36 numbered sections.

Slope County at a glance
Amidon is the county seat, and Marmarth are among the other towns on the county map. Census Bureau estimates put Slope County at about 674 residents in 2023 on roughly 1,215 square miles of land. Beyond the town lots in Marmarth, expect big rural parcels across the county. Slope County was organized in 1914, so deeds for older farms near Amidon can run back a long way.
Using the Slope County parcel viewer as a Slope County township map
On the Slope County parcel viewer, the parcel record for a parcel near Amidon usually lists the township, and many viewers draw township lines as a layer. For the survey grid, look for section, township and range in the legal description on the Slope County record.
Why the township matters
Township lines near Marmarth affect tax bills, local permits and voting precincts, and the county record is the better guide than an address. Assessment and tax districts in Slope County are often tied to the township, so two neighboring parcels near Marmarth can carry different rates.
How the survey grid is numbered
Near Amidon, numbering starts with section 1 in the northeast corner, with the count snaking back and forth to 36 in the southeast. Aliquot descriptions for land near Marmarth are read from the end: find the last quarter named first, then work inward. Water, old surveys and corrections can leave odd-sized lots along section edges in Slope County.
Old names and overlapping districts in Slope County
If a county deed near Marmarth cites a township that no longer appears on the map, the county recorder can usually explain the change. Election maps, school districts and fire districts in Slope County don't always follow township lines near Marmarth, so check each one separately.
