DescriptionSometime in the 1920s, Dr. George Ruhle named the Belly River after a translation of the Blackfeet word Mokowanisz (or Moo-coo-wans), which refers to the bison’s digestive system. The Moo-coo-wans name first appeared on the Arrowsmith map of 1802. David Thompson named the river Bull Head in 1814. The river drains the northeast corner of Glacier National Park and flows into Canada.Personal NamesRuhle, GeorgeThompson, DavidOther Name(s)MokowaniszBull HeadContributing InstitutionMontana Historical Society Library and ArchivesGeolocation[1] CountyGlacier National Park
