Closures for Peregrine Falcon Protection MORE INFO >>>


Begin at a large Black Oak with branches touching the cliff. Lieback wide crack to easier ground. The bolt anchor noted in the Supertopo guidebook is no more, so bring some smaller gear for an anchor, or continue up to the belay/rap tree for Grant's Crack.


Left and around the corner from Grant's Crack.


One or two large cams, plus a few extra pieces.

Watch your head on the trees. Also, I found it was a difficult location to build an anchor.

Correction to the Supertopo: the bolt anchor indicated for Oak Tree Flake and Grant's Crack on Swan Slab (page 98) is gone. Instead, go ~20' higher to a small tree with webbing/rap rings.

We went up to the tree when we discovered the bolts missing. To TR this for our group we had to belay beneath Grants crack. The slings on the tree were good, but there was a rap ring that had nearly been worn through. Luckily some kind soul left a quick-link we could use.

The flake is real easy but the first move or two from the ground up the crack directly below the right side of the flake are a bit tough for 5.6. It's easier to climb to the left, then traverse right under the flake. No need to build an anchor--simply sling the tree limbs at the top of the flake. Not good for the tree, though.

Try building an anchor from the stacked blocks at the bottom of the Bay Tree Crack.

Nice moves up the flake. If you don't have a #4 it's pretty runout to the branches. Should have read MP first about the anchor. I spent a while looking for the bolts. Climbing up to Grant's Crack anchor added a few more interesting moves.

Yep, like you said, bolts are gone. I didn't go up to the next tree, just built a quick anchor with no. 1 and no. 2 placements at inside corner left of old bolts. Came here right after Jamcrack, and the bottom moves are easier than that.

People were TR Grant's crack, so I didn't bother heading up to the tree. I was able to put in two #1 C4s and one #3 after digging out a crack near the old bolts (I believe left of the crack mentioned by the previous poster). I would recommended belaying from the blocks as mentioned by another poster and then continuing up Bay Tree Crack! Walk off to penthouse cracks and rappel, or in our case rappel off the tree :/ (people were TR penthouse cracks and we didn't feel comfortable with the final descent.

Led it twice over two days and ended up placing the exact same gear in the exact same spots. Basically, place a green #0.75 BD C4 at the start, then a #4 BD C4 halfway up the lieback flake, then finish with a red #1 BD C4 just past the tree branch before the topout.

The note in the description is correct. There are no longer bolted anchors. Save yourself the hassle of looking for a good anchor past the second tree, and just build a rappel station there. (You can do this all in one pitch.)
