L to R R to L Alpha
Of the three aretes, this route follows the middle one. Starting at the base of the arete there is a high first bolt that many may chose to stick clip. Some balancy but not difficult moves will get you to the first bolt. From there, a more difficult move gets you to a large hueco where you can clip your second bolt. The crux comes at the top after clipping your third and final bolt.
Three bolts to a two bolt anchor.
