Denali: Sourdough Couloir

Just finished rereading Jonathan Waterman's excellent book Chasing Denali. I highly recommend, especially if you are someone who has spent time on or around this magnificent mountain.

I was reminded of the striking fact (as of time of publication) that nobody has repeated this route since 1910. This is the most recent pic I could find of the entire couloir. The North side is remote, but the Harper Glacier is accessible from Denali Pass. Likely quite skiable under the right conditions.
