South Dakota has some Walk In areas administered by the State. I am not sure of the exact program name, but maps are available through the state. National Grasslands are open to hunting for various upland birds. Indian reservations can furnish guides and usually require a Reservation License. The Black Hills may have a few grouse, mostly spruce grouse as I remember. The Black Hills are probably not worth one's time as bird populations are tiny. Access can be found on Forest Service maps. West of the Missouri, some pheasants can be found in areas with waterways and creeks, but the bird density is nowhere near that of the East River areas. Ranches in the West River area tend to be quite large as the land is relatively dry compared to the East River.
