Thanks... Yeah I posted that article on my website cos I was surprised. That boy hiked the trail to Angel's Landing several times, yet just this one time he slipped to his death. It was pretty sad! Angel's Landing is indeed one of the most dangerous trails at Zion. Levionian, a member here, used to work at Zion and he said he ascended Lady Mountain and said it was so dangerous.
I checked the park info (yeah I keep everything!) and there IS a Weeping Rock. It's not a major trail but takes you to this cliff where the water weeps out of it. I hiked to all three levels of Emerald Pool, but the top one was best of all cos it has a great waterfall coming through this high cliff. It's really cool there.
I agree with you, I'd like to hike up Hidden Canyon Trail to Observation Point too. I didn't go all the way at Angel's Landing because it was really the first time I ever did mountain hiking, and wasn't used to cliffs, height and so on. Now, I am getting used to it, and after climbing Mt Timp, I think I will have less fear.
