Shuksan NE Rib via the Sulphide

[Toast]

Anybody have info regarding the NE Rib on Shuksan's Summit Block from the Sulphide Glacier? Beckey describes it from the NF approach. I haven't seen anything about coming around the east side off the Sulphide. From pix it looks like there may be a sizable moat and steep terrain to traverse initially when getting onto the Crystal Glacier. Anybody done this via the Sulphide approach? Any beta would be much appreciated.

 

Thanks,
