This topo is very helpful. One observation I have is that there is a mandatory hook placement in a drilled hole between the fixed pitons near the top of Pitch 3. The hole is not obvious from below. Since John does not show the hook placement on his topo, perhaps there was an angle piton in this hole previously.
This is a really cool topo. Thank you for posting it. It is great to see the actual write up from Ron about his great contribution to Zion climbing. That guy knew early on that pounding sandstone cracks with pitons is not sustainable.
