Type:
These three small, geologically connected Cenozoic and Mesozoic foreland basins are grouped for convenience into one basin. Within these basins is also included the Ashland Syncline. These basins are bordered on the south by the Lake Basin Fault Zone, and the Big Coulee–Hailstone Dome, a series of small anticlines separating the Crazy Mountains Basin from the Wheatland Syncline portion of these basins; on the west by the Little Belt Uplift; on the northwest by the southeast plunge of the Sweetgrass Arch; on the north and northeast by the Moccasin Mountains, Big Snowy Uplift, and the structural saddle between the Bull Mountains Basin portion and the Sumatra Syncline; and on the southeast by the structural saddle between these basins and the Powder River Basin.
