Braided Stream Deposit in Narrow Valley

Braiding is caused by random deposits of the coarser fraction of the river's bed load when the snow and ice melt ends. Deposits are constrained by the valley walls until they reach the Peel river, where they form a fan delta. The numbered arrows point to numerous landslides in the valley wall. The idealized cross section shows the interlaced lenticular nature of these braided, sand and gravel deposits (Sowers, 1976). Home
