I did a day hike from the Portal yesterday (Sunday 10/8) and my group had a couple of paper bags stashed in a bear box at an overnight parking lot. When we retrieved our bags at about 4pm, my toiletry bag must have fallen out or something because it wasn't in the paper bag when I got back home to San Diego. We used the farthest bear box on the right (north) of a row of several boxes, right under a restroom. The bag left behind is a North Face travel canister (black color, looks like a mini duffel bag, 9x5x5 inches):

I asked the visitor center about it and they said they are done sweeping out the bear boxes for the year.
