Thanks George. I will play around with some software on the originals. The pictures you see are without any editing.
BTW. That photo shows the "snow flutes" I tried to describe in an earlier post. Nick is just about to descend the steep leeward side of one and the white strip behind him is the steep side of another. Since the climb, I went on the web and read other accounts of climbing the N. Face. They were all done in the fall with more icy conditions and most state the final couloir is the crux. At this time with the face covered with snow, the crux is BY FAR the traverse below the final headwall. It is much steeper than the rest of the climb. While not difficult, it is certainly the "mental" crux.
