Crouch start below the blocky overhang with a right hand jug rail and left hand slapping the left arete. A mix of powerful moves, technique, and lots of squeezing are need to gain the lip. The top-out to the left is equally devious.
Traditional beta is to go left at the lip and mantle. I figured out this beta first, but tried the other way after I did it. Both feel very similar difficulty wise in good conditions, right exit felt better when it was hot and humid.
