I've spent more than my fair share of time in Morton County, as a result, I've spent a considerable amount of time on the grasslands. At roughly 108,000 acres, it's a lot of ground to cover. In a nutshell, it's a tough hunt, but it can be a good hunt.
Here's what I can tell you:
1) It's hard on dogs. There are "things" there that can cause significant issues with a dog's health. This includes rattlesnakes, cacti, old machinery, unseen barbed fences, and rock outcroppings.
2) You'll need plenty of dog power. I don't want to get into a range discussion, but the grasslands are a good place for an all-age pointing dog. The more ground you cover, the more likely you are to find birds. This is a wide open space with few roads, if you don't know where to look, you're going to have a long day.
3) You can try the river....but so does everybody else.
4) The weather can/will wreak havoc on your dogs. Morton County is actually high desert. At approximately 3400 feet, the air is dry....very dry. Scenting conditions can be tough. It can also get hot...even in January. I've seen plenty of 60 - 70 degree days in January. Obviously it can get dang cold as well.
5) The wind will blow. If it blows hard, you'll need some eye protection.
6) If your dog's feet aren't tough, don't go. You can boot, but it cuts down on range and stamina.
7) Stay away from the snake areas when it's sunny and 40 degrees or above. They come out in droves and lay on the rocks. They're slow this time of year, but they can still bite.
8) Small animal vets are not handy, so it's a bit of a gamble.
9) You'll likely stay in Elkhart, make a reservation as they fill up quickly....even during the week.
10) Bring plenty of water for your dogs while hunting. Whatever you think you'll need....double it.
This may sound like a terrible place to go, but it's actually a wonderful place spot. Some of the best memories I've had as a hunter have been there. Beauty is in the eye of the beholder, I think it's one of the prettiest spots on earth.
Don't expect to shoot limits, but it does contain some birds. Scalies are there, but are not the norm. However, like bobs, I've been hunting the same coveys for years. On of the main differences is the range. A scaled quail's range is significantly great than that of a bob.
You'll also find scaled quail in the sand hills south of Garden City. It's very common to see scalies on Southwind golf course.
Good luck,
Point!
