For westside of OP, there's likely to be a number of types of berries at once. And then the difference between one drainage and the next, north facing vs south and the same type could be ripe a month apart. The berries I find the most, fresh sign is usually thimbleberry. But it usually isn't from the biggest bears. Biggest bear poops seem to be by salal or cascara ( from what I find).
Likely to have thimbleberry, blackberry, cascara cherries, choke cherries, salal, huckleberries, salmonberry, raspberry and elderberry all in Aug and September. If it's really hot I don't see the bears much during the middle of the day. Usually see them before 9 and after 4, but occasionally see one in the road at noon.
I see most early season looking down in clear-cuts that have buffers for streams at the bottom. I don't see lots of berries down there, other than salmonberry by the water and scattered huckleberries in the buffer. So, probably headed high in the cut to the big patches.
