Hi, for those who have done both, some perspective on what is more frightening or scary - and degrees of difficulty.
We did Highland Bowl in huge snow conditions but frozen harder than Vermont Ice and parts of the ridgeline - were so narrow with both steps of the Yeti - hands and knees sometimes for us but we made it. If I knew how hard that was, Dad (me) would have opted out. Bob Barnes took us up and was incredibly motivating and also graciously carried my boy's skis as young man, all 58 lbs of him was lay prone after that most hairy part around the hut and thereafter!
Anyway, any comparative views are solicited. I know there are harder bootpacks like in the Dolomites - Sasso Pordoi area where a rappel is mandatory and one hikes over precipices of rocks on a narrow ledge of snow and ice..but these two, Highland Bowl and Kachina seem somewhat comparable as inbound terrain and hence query - thanks
