Cabbart soil series
Cabbart soils cover 2,730,099 mapped acres, mostly in Montana, North Dakota and South Dakota. USDA rates shrink-swell a limit for houses without basements on under 1% of that land, and a shallow water table a limit for basements on 0%.
It is the leading soil series by area in 6 of the counties and cities on this site, including Golden Valley County, MT; Fallon County, MT; Musselshell County, MT.

USDA's description
The Cabbart series consists of shallow, well drained soils that formed in material derived from semiconsolidated loamy sedimentary beds at depths of 10 to 20 inches. These soils are on hills, ridges, escarpments, and sedimentary plains. Slopes are 2 to 75 percent. Mean annual precipitation is about 12 inches, and mean annual air temperature is about 43 degrees F.
