We used webbing on the boulders/rocks at the top of rappel one, then came back for it.
We found TONS of webbing at the last drop and used that. The piece around the tree looks older, the piece between the tree and the drop looks very new. When you're standing at the rappel looking down canyon, you will see incredible grooves. Consider taking a couple steps right (it's awkward, but whatever) and going from there to avoid grooving the rock even more.
