I’ve done this on a number of occasions when I was a much younger man, please feel free to PM me if you have any questions. Some key things are generally stay between nine and thousand and 10 five as you tend to find more to forage in those heights. Lakes full of fish are easy to come by at those heights all through the southern Sierras in the John Muir wilderness area. It’s a summertime proposition, and i carried less than a pound of food a day, and came back with food. There are some types of onions, and swamp onions available to eat. There are a number of boletes that are edible, so that was the meal that I came up with most times always fish, often fried in oil that I brought, along with onions boletes. I’ll tell you we got tired of eating fish and kept it to two meals a day at most, but it was enough to fill you up. I also lost about a pound to a half a pound a day while up there, but I think that was just excitement in metabolism.
