The river begins at the outflow of an unnamed lake at an elevation of {{convert|382|m|abbr=on|0}} and flows west into Sussex Lake, then north to Muskox Lake, at the border between the Northwest Territories and the Kivalliq Region, Nunavut, where it takes in the left [[tributary]] Icy River. It flows over the Muskox Rapids, takes in the [[Tributary#Terminology|left tributary]] Contwoyto River, and heads east through the Heywood Range. The Back River heads over the Malley Rapids, takes in the left tributary Siorak River and enters the long lake-expansion [[Lake Beechey]] in a southeast direction. It heads east, takes in the right tributary Baillie River, left tributary Warren River, right tributary Jervoise River, passes over the Hawk Rapids, takes in the right tributary McKinley River and right tributary Consul River. Between the Baillie and Consul Rivers, the Back River forms the northern border of the [[Thelon Wildlife Sanctuary]].<ref>{{cite journal|last1= Currie|first1= Douglas C|last2= Giberson|first2= Donna|last3= Adler|first3= Peter H|title= Insect biodiversity in the Thelon Wildlife Sanctuary|url= http://www.biology.ualberta.ca/bsc/news21_2/arctic.htm|journal= Newsletter of the Biological Survey of Canada (Terrestrial Arthropods)|date=Fall 2002|volume= 21|issue= 2}}</ref> The river turns northeast, takes in the left tributary Bullen River, and reaches Pelly Lake at an elevation of {{convert|155|m|abbr=on|0}}.
