Salmonberries are found in moist forests and stream margins from Alaska to Northern California, especially in the coastal forests. They often form large thickets.
Books often call the fruits "insipid", but depending on ripeness and site, they can be quite good and are used for jams, jellies and wines by locals. They were and continue to be an important food for native people.
Salmonberry jam was a plot device in the 1990 movie Salmonberries starring k.d. lang.
