I was going to ask if they're berries, or blue flowers that just haven't opened yet? Can't really tell because the pic is a bit blurry. Looks more like a flower scape to me. The blue ginger - dichorisandra - is actually in the spiderwort family so it's more hardy than the tropical gingers. Spiderworts do grow up there (I am from BC originally). My pic is a start of a blue ginger I got from a friend, foliage is similar to your pic.
Not many berries that are that blue, except blueberries, of course. Foliage is wrong for wild blueberry or huckleberry. Not Oregon grape, either.
Call your friend and tell her to go on that hike again so she can get another picture??
