Thanks for that… I had not read it and that helps… looks like the author is recommending East Booth Pass.
I wish I could help you a little more, but I never really knew I was near Eisemann Hut until it was all over and I looked back at what had happened later. I never actually saw the hut. I had hiked in from my house in Frisco on the North Tenmile trail… over Eccles and Red Buffalo passes, through East Vail and up the Booth Creek trail all on day one. It was late afternoon before I crossed over what I hoped was West Booth Pass, only to realize I had made a mistake.
I just remember bushwacking a few miles down a very steep forest before finding some diamonds nailed to trees. After camping I kept following the diamonds the next morning until they eventually came to a more well-defined trail that took me out to Vail. I came out by some horse-stables.
Thanks again for the link!
