Yes, it is ok. But I have also seen packs there with holes chewed into them by the Marmots.

So open pockets, etc, and store all food and such in a canister placed OUTSIDE your pack, or take it on your back.

Good point. Will do. I got a neat lightweight Gossamer Gear Riksak for a day pack for the summit.
