I agree that dealing with a downed elk is a great problem for which we need a solution before getting to CO. For planning purposes, I am thinking that each kill means having to get 3-4 75+ pack loads (meat and maybe hide/head/rack) off the mountain and processed - the same day the elk is taken. As I mentioned in my PM - it appears that it is very hard for a DIY group to hire a good packer during the season - given that is true - it looks to me that every elk taken means at least 2 people spend a day getting the elk off the mountain and to a processor (lined up prior to a kill) for final butchering/freezing for transport home. The problem gets even more interesting if more than one person scores - especially if the kills happen at (roughly) the same time. As an FYI, I am planning on staying the entire trip - even if I score an elk on day 1. If that happens, it is my intent to hunt with a camera the rest of the trip - either by myself or helping someone else get an elk.
Another problem area is food. Figuring 4 people (working hard) in the hunting party - for every 7 days in the field - we will need 84 filling meals (plus snacks?) that have to be acquired, humped into camp, stored (in bear country?), cooled (for perishables), prepared,and cleaned up. Without getting overly specific - are we talking about eggs or pancakes, meat and coffee for breakfast, sandwiches/snacks from day packs for lunch, and meat/potatoes/etc for dinner?
Obviously, everything that goes in, comes out - 4 people over 7+ days makes a proper field latrine an issue as well.
As thirst at altitude (while working hard) is a serious issue - we will also need potable water for the 7 days - for drinking, cooking, and cleaning up.
A closing thought - my experience (deer on the East coast) says that detailed planning before the hunt means a much greater probability of a good hunt. Put another way, I want to sweat the details now - so I can be free to live the hunt in CO 2010.
