Streamside plant identification - Oregon
It's a plant in the family Ribes, which includes currants. 

If it stinks when you crush the leaves, it is probably Stink Currant, or Ribes bracteosum, a plant found in the Pacific Northwest.


  Leaves are large, like maple leaves, sparsely hairy to smooth, with 5 to 7 lobes, stinky when crushed.  Flowers are numerous on mostly erect clusters; with white petals and brownish-purple to greenish-white calyces.  Berries are blue-black with a whitish bloom.




The leaf and berry are a good match. There are ~150 species, so it's a bit difficult. 

It could also be Ribes acerifolium, or Maple-Leaved Currant.


  Shrub with spreading branches but no bristles. Leaves maple-like, 1–3 in. across, with 5–7 rounded, finely toothed lobes. Hanging stem of 8–12 greenish flowers, each less than 1/3 in. across with tiny red petals and stamen filaments broad at base. Berry black, coated with bluish powder. Grows from mid elevations to treeline in Cascade and Olympic mountains.




I could not find a photograph that was not copyrighted. The flower color was pinkish to brownish.

It's not a perfect identification, but it's closer than 'in the ballpark'. If you google "Ribes western Cascades", you'll see what I mean. :)
