I think getting past the initial crack seemed to be the crux. It is a fun romp up to the top. Use caution at the end; we did clean some loose stuff on the right of the arete; Mike went left and I went right to top.
Walk to slick slot at end of the wall, pass Uberfall and the crack is up and left at top of slot. Look for a layered slab to a hand crack then continue to anchor. Anchor biners
single rack cams, nuts, slings and QDs; large slings for top. I slung the very top of the arete.
