Running a Sioux County land owner map step by step
Use the Sioux County Portico map for a county land owner map; addresses, names and parcel numbers all work around Cannon Ball.
Where the parcel data lives
Parcels around Solen are published on the Sioux County Portico map, which opens without registering. When a rural tract has no street number, follow the nearest road on the aerial until the lines appear, then click inside the one you want, which applies near Cedar Creek as much as anywhere. For a home near Cedar Creek, write down the parcel ID from that panel; every clerk in the county will want it.
Taxes on the record
The record for a parcel near Cannon Ball often lists value and tax amounts; the Director of Tax Equalization sets values and the treasurer or collector bills taxes.
Legal descriptions in North Dakota
North Dakota follows the Public Land Survey System, so deeds around Cedar Creek reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Fort Yates can be irregular. Write down the legal description for the tract near Porcupine for any title or survey request.
Trusts, estates and LLCs
For land near Cannon Ball, the record lists the owner of record, and that isn't always a person. An estate listed as owner near Cannon Ball usually means title hasn't passed yet after a death, and the executor handles questions.
Sioux County in a few facts
Fort Yates holds the county offices, home to the main records offices. Smaller places on the map include Selfridge, Solen, Cannon Ball, and Porcupine, each with its own cluster of lots. Roughly 3,643 people live in Sioux County (Census Bureau estimate, 2023) across roughly 1,094 square miles. Sioux County dates to 1914, so old deeds can run back a long way. Places such as Cedar Creek, Missouri River, and Cedar River National Grassland make handy reference points on the map.
Land on the county line
Sioux County meets Adams County, Emmons County, Grant County, Morton County, and Corson County, SD; every one of them runs a separate parcel map. Acreage along the edge near Selfridge may be split in two county records, so check the neighboring map as well.

Looking around the parcel
Look at adjoining lots near Cannon Ball to see who owns the neighboring land; it helps with access and boundary questions.
Deeds behind the record
For land near Lake Oahe, a viewer entry isn't legal proof; for that, pull the deed from the County Recorder.
A word on accuracy
Out toward Cannon Ball, the acreage figure is an estimate; only a licensed surveyor can set the real corners on the ground. On ground around Selfridge, records update in batches, so a deed recorded last month can take weeks to appear.
Reaching an owner
A polite note sent to the tax-bill address works better than knocking unannounced for land near Cedar Creek.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Solen, so load it before you lose signal. A screenshot of the parcel near Fort Yates with its ID helps when you meet an owner or agent.
Backing up the map with records
On ground around Fort Yates, the map is an index, not the title: recorded deeds, plats and easements for parcels in the county sit with the County Recorder. Out toward Fort Yates, use the instrument number shown in the record panel to skip a name search.
Offices that can help
Recorded documents for a parcel near Lake Oahe come from the County Recorder, sometimes only in person. Building or septic questions for a lot near Porcupine need the planning or permitting office, depending on whether the land is inside town limits.
