Tree Climbing: Ascending with Doubled Rope Technique

This videos illustrates one of the ascending techniques used in the Cornell Tree Climbing Institute's instructional classes. This information is not intended to be an online tutorial for beginners. Our intent is to share these general procedures with other qualified professionals who are interested in developing a college-based recreational tree climbing program. Tree climbing can be hazardous! If you are new to tree climbing, seek qualified instruction before attempting these techniques. CTCI does not advocate unsecured footlocking, as there is no connection to the rope. CTCI also does not advocate secured footlocking as there is no redundant connection to the rope. CTCI does not teach the double ascender method for the same reason. These styles are presented merely for the sake of comparison to the Blake's Hitch method, which we do use regularly.
