Angel's Landing is the sort of trail that would probably never get built today. The last section of the trail goes along an extremely narrow ridge with 1000' dropoffs on both sides, with only an occasional chain to help you keep your balance. I was last here when I was 12 or so, and was too scared to complete the trail. Thus, there was extra significance behind my return to the trail. The challenge bar had been set a lot higher though -- in winter this trail is snowy and often icy, and the snow is often deceptive in hiding cliffs, crevices, and other dangerous locations. I bought some Ice Trekkers traction control devices for my feet, but they turned out to be somewhat inadequate in dealing with the worst situations -- slick icy slopes. It's hard to get a good view from a distance of this last part of the trail, but I did manage to take a very zoomed in picture from another trail that gives a sense for it. If you look really close, you can see a person making her way along the ridge.
Fear was my constant companion as I made my way across. I was acutely aware of the tiniest slipping of my feet, and moved extremely carefully as I contemplated both the physics of my motions and my intuitive rock climber sense of my movement. Having this extended exercise of constant fear let me play with how I dealt with the fear; this situation was a reasonable one in which to be fearful, but some flavors of fear are more productive than others, and I was able to analyze what generated the different types of fear.
I met some other people with better traction control devices -- I had chosen a good all-around solution that handled all kinds of terrain, but the trail really demanded long spikes for better control on ice.
I climbed up the tree at one of the peaks and surveyed the view. It was a hell of a drop. The view was fantastic though.
Angel's Landing isn't the only harrowing hike in Zion. Here's Hidden Valley:
