Marked on a map as Moose Jaw Bone Creek in an 1857 survey by surveyor John Palliser, there are two theories as to how the city got its name. The first one is that it comes from the Plains Cree name moscâstani-sîpiy meaning "a warm place by the river", indicative of the protection from the weather that the Coteau range provides to the river valley containing the city and also the Plains Cree word Moose Gaw meaning warm breezes. The other is that on the map of the city the Moose Jaw river is shaped like a moose's jaw.
