If you go for Shuiksan via Sulfide you'll find pretty good conditions. I did it last week. Snow starts down in the trees below Shannon Ridge. The Notch has a few cornices. Good camping at 6500, toilets are not melted out. Despite clear nights last weekend, snow did not harden and was soft on climb and VERY soft on descent (postholing above the knee). The Southeast Rib was a good climb - it's all melted out. A few of the gully rap stations were still covered and I couldn't find them all.
I've got work this weekend, otherwise I'd do something with you. Hope you have a fun trip.
