In addition to what you mentioned, maybe a small poncho or something to string up in case you wanted to stay dry during a down pour, first aid supplies for the minor things, map & compass, fire starting materials, maybe a cell phone if it gets coverage. I'm keeping this small, not knowing how much you want to carry or the size of your pack. I carry a lot, probably too much, but I like the extra weight as a work out during my hikes. Plus if need be I can always use anything extra I'm carrying. I read a lot on emergency and wilderness survival. There are so many different ways to be prepared while out in the sticks. Everybody has their own favorite things to carry, There are some basic items but you need to use a little trial and error to see what else you may want to bring.
