Nathan,
Thank you for sharing a wonderful recount of your hunt. I got a heck of a laugh out of your narrative. It gave me vivid memories of the first pack in hunt I did with my best friend and roommate from college. I remember all of the anxiety and trepidation and worry that comes with having horses in the backcountry, trying to get a wall tent up, and so on. The first time you look at that big pile of gear, and are contemplating how in the world you are ever going to get it packed, balanced, and loaded on the horses is a pretty daunting moment.
Those are some fantastic pictures, and yes, that's some steep country. I can't believe how open that country is, it's truly spectacular. Those are some amazing and treacherous looking waterfalls too.
Just curious, why were you filtering water for your Mountain House? Why not just boil it? Also, for a setup with horses, you'd be much better served with a bag/gravity filter setup instead of pumping everything.
Get some trekking poles. Get a set for your buddy too.
Congratulations on what looked like an epic hunt.
