This route is on the Northeast corner of the Thumb. Approach via the standard trail, then go right down into a low spot and back up onto a huge shelf below a light-colored North-facing wall. The Zig Arete climbs up and left to the left hand arete and up to a 2-bolt rap anchor. The climbing is quite good, with large moves between big, positive holds, and quite easy at the given grade of 5.10c. Great pitch though!

Six draws and some slings for the anchor up top- 2 Metolius rap-hangers.

In the guidebook this is a 10c, maybe it is rated easier here because of the many jugs. Crux for me was figuring out how to clip the last bolt and crank on thru.

On my first try, it took me forever (and falling) to figure out the crux. I thought "No way is that 10c, it's way harder". Now that I have beta that works for me, I think "No way is that 10c, more like 10b". My conclusion? Zig Arete is a difficult onsight, and 10c is a fair grade. The beginning is on jugs, but the crux is what makes the route.
