Alois Smrz and I climbed this route in August, 1990. After a bivouac on the Grandstand, we climbed the Italian Cracks variation to the Second Ledge. We then "walked" around the corner to the NW Face. We climbed the face to the left of the Great West Chimney. There was an old ring-eye piton in a belay alcove at the end of the second or third pitch. It is possible we finished on or near the top of Durrance's West Face route. If I ever digitize my old slides, I will post them here.
We did the North Ridge with the chimneys. I was surprised to not find a route page for this classic climb after all this time so I'm adding a few old photos from our climb of the original route. And I agree, this side of the Grand has some of the finest routes in the park.
