This treed flank was chosen for ascent due to the team having limited glacier/crevasse gear. It's steep and difficult but it went. We chose to go light so this route was chosen to minimize our exposure to crevasses. The toe of both the Eagle and Uto glacier's are more serious but if your team has the gear, they are both fine routes. A team that did the traverse two years ago finished via the Sir Donald / Uto Col.
