This isn't exactly on top of Henry Pass, rather it is a bit downhill from the top. The winds were so strong on the pass, that I didn't want to take a picture from there. I had to descend slightly to get out of the winds before I stopped to take a picture. Once I got out of the wind, it was back to being a perfect, beautiful day.
The track drops sharply to the left (over the waterfall I describe in the text) and then follows the left side of the valley before going over to the right side. The track crosses the slip that you see here. At the bottom, the slip is 60-70 meters wide. Knowing its width, look at how far up the mountain it reaches. You can't actually see the top of it as it goes behind a ridge in this picture. It looks fairly smooth from here, but there are massive boulders that fell from the mountain. After the slip, the track follows the valley left and then right around the ridge at the center of the picture. It is past the ridge that Katherine Creek begins and I would follow it all the way to the sea.
