Escape Route from North Klondike Couloir

Should conditions warrant an escape from the snow climbing in North Klondike Couloir (for example, I had an ice axe but no crampons and couldn't make the final very steep stretch without them), this section on the right side of the couloir near its upper end holds many Class 3 options. In the middle of the couloir, where it is also narrowest and quite steep at times, the escape options are Class 5. I exited above this point, maybe about 50 vertical feet below the cornices.
