That area can be very fun to hunt. I hunted that area from about 1992 - 2010. Before the water returned it was fantastic area to hunt. Once the sloughs refilled it was still fine, but much cover was lost. Mostly shorter grasses (huns and sharptails prefer) which lends itself to being able to watch the dogs work.
Man that is remote country though (although I suppose the Bakken has changed it some). Divide and Burke Counties have about 2,000 people each. If there is snow ... take care what roads you travel, keep your gas tank full, and some survival gear in the truck. Odds are you will never need it, but finding help can take some time. Assume cell service is much better now than say 15 years ago.
We were fortunate to know a working farm / ranch in eastern Divide county. Decent private land hunting and someone to call if we had a problem. Helped them drive cattle a couple times to the home place in late October.
Yes, I learned some time ago to be very prepared when out in remote ND. I learned to carry all things with you in a truck and have good up to date maps, because I was one of those people that got stuck and stranded.....Not fun!
But I love that area that is so remote because the hunting is great!
I lost an oil pan on a secondary road(not a 2 track) up there a couple years ago. For good or bad the Bakken has improved the cell service. Still was a long tow and than a much longer wait in the small town to get a new pan from Billings. Oil field activity has tapered off the last couple years so there are less roads open after a snow now. As everywhere the crp has declined.
Many small ND towns have a campground (even those with just a hundred people). It will likely have electricity, but you maybe on your own for water. May want to google search Divide county campgrounds and follow up with a phone call or email. I would hope that the city campground up there are not permanent residence type places. Not sure if they shutdown for winter or first snow either.
Other private "campgrounds" up there may cater to oil and oil service types. Noise, crime, rowdy behavior, etc... is not uncommon there.
Crosby fairgrounds free camping with electricity and water and hot showers. Hunting really good, but remote. Keep jump starter pack in the truck, scoop, tow strap, extra key, and prepare like you will spend the night in the truck, buddy heater, sleeping bags, food, water. Cell service iffy. I camped up there for a week last fall and great fun and good hunting. Moose, swans, geese just made it great. If late in the season you can shower at the truck stop on the highway. I was headed that way but the hunting in SD kept me from crossing the border. Maybe next year.
