• Nuts, dried fruits, and chocolate for calorie-dense options.
• High-fat foods like cheese, salami, and nut butters to provide sustained energy.
• Consider bringing vitamin supplements to prevent deficiencies.

Meal Planning

Plan meals that require minimal preparation and fuel. Test your meals beforehand to ensure they meet your taste and dietary needs.

Water Sources

Melting snow is the primary method for obtaining water:

• Use a dedicated pot to melt snow over your stove.
• Add a small amount of water to the pot to prevent scorching the snow.
• Purify water by boiling or using purification tablets, especially if near wildlife areas.

Do not eat snow directly; it lowers body temperature and can lead to hypothermia.

Hydration Tips

Stay hydrated by drinking regularly, even if you don't feel thirsty. Use insulated water bottles or hydration packs with insulated tubes to prevent freezing.
