Back in 2014, David Roetzel became the first person to solo 15 of Vail, Colorado’s major ice routes in a single day.
Some of the climbs were moderate on the moderate end, around WI 3, others pushed expert territory, around WI 5+.
In an interview on Outdoorresearch.com, Roetzel said of the project, “The biggest variable, The Fang, came in this year  in excellent form and I am climbing as well as I ever have been. … I soloed The Fang for my first time and had fun doing so. After soloing The Fang, I felt that this dream of mine was within my grasp and began to plan for it for real.”
