Mt Whitney Zone Forums General Discussion Ursack failure near Mammoth Lakes

These pictures prompt several questions.

1. One of the sacks (the really dirty one) does not appear to be an Ursack White, the one recommended by the manufacturer as being bear-proof. What was it? Ursack also makes less capable sacks that will only deter squirrels and marmots.
2. Were the Ursacks tied correctly at the top?
3. Were the odor proof inside bags in use?
4. Why in the heck was a little red stuff sack tied up with the Ursack? Was there food in it? That in itself would be enough to encourage the bears(s) to really go at it.
5. All the sacks should have been counter-balance hung...as recommended by the staff at White Mountain ranger station in Bishop. Just leaving them on the ground is an invitation to the bear clan.
6. Where did this actually happen? In the town or elsewhere?
7. The trash appears to have been very neatly laid-out, as if on display. Mr. and Mrs. Ursa would never leave such a tidy looking mess; they'd just let things fall in a heap. This is very suspicious to me.

I've been using the Ursack this season (six overnighters) in the Inyo National Forest (avoiding Mammoth), and have had no problems. But I take extra care to follow the manufacturer's explicit instructions.

Okay, what are your opinions? Anyone else use one? Where? I'm sure someone out there will know better than me about Ursacks.
