You found the Jimmy Buffett shrine. What is interesting about this one is that he is still alive while all other shrines are for people who are not. When Tony Crocker and I were at Ajax two years, we found John Denver, Marilyn Monroe, Elvis Presley (and it was the King's birthday) and Jimi Hendrix, who has the best one although it requires black diamond skiing to see it. I also have directions for Jerry Garcia and Jimmy Buffett shrines and could lead a tour of them on Saturday if anyone is interested. For more info, see aspensnowmassshrines.com
I found the Hunter S Thompson shrine at Snowmass today, the only one I was looking for. It's on ridge below Gunnar's View and located there because of Thompson's fondness for guns. There were at least three trees with a lot of decorations.
