==Geography== The Twin River originates from the meltwaters of Twin Glacier, a valley glacier that flows from the Andrei Icefield which dominates the mountains north of Twin River and from which numerous glaciers extend in all directions. This large glacial field is named after the son of Olav Mokievsky-Zubok, a glaciologist who carried out significant glaciological work in the Coast Mountains from the 1960s to the 1970s.<ref name="GE">{{cite book|last1=Kargel|first1=Jeffery S.|last2=Leonard|first2=Gregory J.|last3=Wheate|first3=Roger D.|last4=Edwards|first4=Benjamin|title=Global Land Ice Measurements from Space|chapter=ASTER and DEM Change Assessment of Glaciers Near Hoodoo Mountain, British Columbia, Canada|publisher=Springer Science+Business Media|pages=353, 354, 355, 364, 365, 367, 371|year=2014|doi=10.1007/978-3-540-79818-7_15|isbn=3-662-50130-9}}</ref>
From Twin Glacier the Twin River flows south through glacial meltwater lakes, then through a coastal western hemlock forest. About {{convert|3.5|km|abbr=on}} north of the Iskut River the Twin River is joined by its west fork tributary, flowing south from another lobe of Twin Glacier. This lobe surrounds the northwestern base of Hoodoo Mountain. About {{convert|6|km|abbr=on}} north the two lobes merge in the main body of Twin Glacier. Although the forks are similar in size and flow, Canadian NTS topographic maps and databases like BC Geographical Names identify the east fork as the Twin River while leaving the west fork unnamed. From the confluence of the two forks, the Twin River continues south through an increasingly braided channel before emptying into the Iskut River.<ref name=acme>{{cite web |url= https://mapper.acme.com/?ll=56.50065,-131.38083&z=10 |title= ACME Mapper 2.2 |publisher= ACME Laboratories |accessdate= 20 September 2021}}</ref><ref name=toporama>{{cite web |url= http://atlas.gc.ca/toporama/en/index.html |title= Toporama (on-line map and search) |work= Atlas of Canada |publisher= Natural Resources Canada |accessdate= 20 September 2021}}</ref><ref name=mapbook>{{cite book |last1= Mussio |first1= Russell |last2= Mussio |first2= Wesley |title= Northern BC Backroad Mapbook |url=https://books.google.com/books?id=pBAFEAAAQBAJ&pg=PA51 |accessdate= 20 September 2021 |date= 2018 |publisher= Mussio Ventures |isbn= 978-1-926806-87-7 |pages= 73, 88}}</ref>
