Re the Bearikade--start here and page down to the posts by Greg Mihalik:
Reportedly black bears have become a problem in a few areas of the Winds, mainly Cirque of the Towers and Golden Lakes. There was a big scare with a grizz at Green River Lakes a couple of years ago when some idiots left their ice chest on the picnic table. Grizz do inhabit the territory above timberline in late summer, looking for seeds of the whitebark pine. With the bark beetle plague, that food source is becoming disrupted, which disrupts the bears' habits. Yes, they're around, even if you don't see one. I saw grizz tracks in the Winds--quite impressive. I have never seen a black bear in the Oregon Cascades, but they are most definitely there!
It's fine to talk about national standards, but the bears don't have them! :-) Only in the Adirondacks have bears (black) learned to open the Bear Vault. Containers that stand up to black bear testers (like the Bearikade) don't necessarily hold up under grizz testing. Sierra bears have learned to defeat even the best bear hangs. Elsewhere, the focus generally is to make sure the bears never learn to associate hikers/backpackers with food, which is why Olympic NP requires canisters except where there are existing bear wires.
Please do notice what John said about the weather! A foot of snow was reported in Titcomb Basin two Saturdays in a row, in mid-August, last time I was there, with temps in the lower teens when it cleared. If my dog hadn't gotten sick, forcing me to abort the trip, I'd have been up there for the second one (yes, I was prepared).
