When we go out in the winter we get into snowy areas that require snow shoes or skis, sometimes. We always hike on unpopular trails, and sometimes off trail. So we have a reasonable chance of spending an unexpected night out on one of these day hikes, even though we have not yet. So here is my question. Given no stove, and a chance we will not be able to get a fire going, what is a good emergency food to take that doesn't require cooking? The only thing I have come up with is to take extra GORP and a couple of extra Power Bars. Do you know of anything more interesting? Or less perishable? It would help if it had a long shelf life so I could leave it in my back and use it on many outings.
