There's a good reason why animals hibernate: Winter is a lean season. For both man and beast, the colder air creates a huge drain on a body's energy reserves. If you don't have incoming calories or a massive fat reserve, you won't make it through this season. This fact makes food procurement a much higher priority in a winter emergency than in a summer emergency. Compounding the issue, food gathering is often at its hardest in the winter. Many plant foods are hidden or non-existent, and the animals we would seek for game meat can be scarce. If you have to survive in the winter wilderness, look for these top foods.
