I am starting to plan for my upcoming Yosemite trip so I am reading this thread in more detail. Any other specific suggestions for high cal foods?

I am not much of a cook, so quick and easy beats complicated but more tasty. I can't think of anything that adds up to 6K calories, like Jak suggested. I have about zero body fat, so no reserves-I have consume all my calories.
