Same start position as for "riders on the storm", except after pulling off of the ground make a hard match on the arete, then break on through to the other side of the boulder and climb it on the adjacent blank face and arete. Pretty core intensive compression line that ended up being way harder than I thought it was going to be. Again, if the sit start feels impossible, I'd say try a little harder or just do it from the stand, it's fun!

Left arete of the Milestone
