Planning a solo backpack trip for 1st Season Rifle Elk in South Central Colorado next year. I'll be focusing on hunting and camping in the 9000' to 11000' range. I've been reading everything I can get my hands on and have figured out that most people don't camp out of a backpack tent. I've read enough to know that weather in mid-October at can be anything from mild to wild but would like to hear from some experienced folks on what I should expect on average about the weather. Also, would the weather dictate a four-season tent or would a three-season tent suffice? Any insight on what to expect would be greatly appreciated.
