Course

The Moose River originates about 1.7 km southeast of Moose Pass & flows southeast for about 6.4 km before turning south at its confluence with Campion Creek. The river flows south briefly before gradually turning from south to southwest over a stretch of about 13.5 km. The river than goes south once again until its confluence with Resplendent Creek, which is almost as big as the river when it joins it, after about 7.4 km.
