I have been working on a project with the Green Mountain Club in Vermont and came across this piece of information on their website. It is an excerpt from the 1921 guidebook to the Long Trail.
Note: The last piece of advice
Food List For Two Men For Two Weeks
Flour, 10 lbs. Baking Powder, 1-2 lbs.
Bacon, 5 lbs. Dried Apricots, 2 lbs.
Cinnamon, 1 oz. Dried milk, 2 lbs.
Cocoa, instant, 1 can Succotash, 2 cans
Corn meal, 4 lbs. Butter, 4 lbs.
Pepper, 1-2 oz. Rice, 2 lbs.
Bread, 1 loaf Oatmeal, 3 lbs.
Sugar, 9 lbs. Salt 1 1-2 lbs.
Raisins, 1 lbs. Tea, 1-2 lbs or more
Chocolate, 2 lbs. Salmon, 2 cans
Cheese, 1-2 lbs Candles, 6
The above list is the average of a number of trips, and is suited to the appetite of the author. Some will need more; but it is wiser to reach a food station or the end of the trip just about out of food, rather than to carry several unnecessary pounds over mountain trails - better even to go without a meal due to short commons.
...The wise man goes light.
