We camped at Devil's Garden in Arches in 2024, and were thoroughly warned by the camp host on arrival that the ravens were aggressive around any food left out. Don't leave out one speck.
There was a late arrival at our site who didn't get the message; he lost a couple days of food when he wandered to the restroom leaving his food organization project out on the picnic table. What a mess! There were food wrappers everywhere... I'm glad we weren't there to see it, I can only imagine what it looked like to your neighbor's kids.
