Steep Couloir near Summit
You may see this steep, snow-filled couloir seeming to lead directly to the summit. This couloir looked way too steep for a glissade on the way back down, and I chose not to climb it because it seemed that crampons would be needed, and mine had been left behind. If you want to climb this couloir, I strongly recommend using crampons and wouldn't be surprised if it is steep enough to require more technical gear than that.
