We were on Arch today. We were able to locate where the last pitch started easily enough, but were not as sure about where/how it finished. We ended up at an overhang (with a piton under it) with a crack to the left of it; we laid it back with lots of foot smears. We had to anchor to trees on the path above. Were we off route?
Thanks!

As I recall, Pitch 2 starts on the GT ledge about 10' right of where you climb up from P1. You climb straight up through a small notch (with a tree growing out of the GT Ledge directly behind you) and straight up the face until you arrive underneath the roof. I don't specifically remember a fixed pin, but I usually try to place gear instead of of trusting my life to 40 year old iron, so I forget lots of pins. I climbed as per the Williams guide, i.e. you go out left around the roof and then straight up to the top. I don't recall a laybacking crack though. I seem to remember fairly straightforward face climbing.

Anchors are from a tree, as you found. Walk climber's right and about 15-20' down an embankment to get to the rap anchors.

Long story short: I have no idea if you were off route or not. Hope this helps

You were on route. The last pitch ends at an overhang formed by a left facing detached flake. After that you are on a good ledge with about 15 -20 feet of slab climbing to the trees.
