There were multiple options for rappel on the descent but they are all about halfway on the descent. Look for cairns along the way after following the airy ridgeline and dropping into the gully. After you veer left into the lower gully, look for an eroded foot path to the right that looks loke it ends at a cliff. That's the first rappel with black webbing. I noticed some people missed that and set up a rappel after scrambling farther down. We dropped in at the higher rappel, scrambled down the gully a bit, and found this second rappel which dropped us on the snow gully near the bottom. Without crampons you're looking at an interesting downclimb after this on slippery rock until you exit the gully.
