I know the quality is horrible but I think this shows what conditions you might encounter. There are two climbers descending the upper Koven couloir. I took this with a 1 mega pixel camcorder from our tent way down on the glacier. This was July 20, 2006. The lower couloir had completely melted out and was dry. We climbed this snow to just short of the East Prong Col, the moved to the left on some ledges to gain the col. As I remember the upper couloir snow generally kept getting steeper the higher we climbed.
