Hmm, no performance charts for the Super Cub.
I decided to be a little conservative re. runway length when flying from some of the higher-altitude airfields in northern Arizona. I figured that if the runway at Grand Canyon airport was long enough for the tourist flights, it was probably long enough for me, though! And at least it was winter when I was there.
Agree that mountain flying is a whole load of fun
and teaches you lots about the weather, about piston engine management, and about density altitude.
