Once above Anvil camp we were mostly on skis. We camped up on the plateau below Tyndall.
We skied down to and across Williamson bowl and then skinned up the Williamson west face to just below the rock band. Then booted the rest of the way on frozen snow. On the way back, crossing Williamson bowl, I fell into a waist deep hole of rotting snow near some granite slabs. I was taking my skis off to lay on the slabs for a bit and slipped. It took me a while to get out. Be careful around the large rocks.
On Sunday, we skied down the bowl again and then booted up the steep Tyndall Couloir on the East Face of Tyndall. The north face of Tyndall was holding snow well, but not that deep.
The plateau was easier to cross on skis. There were many areas of snow that were rotten. Even on skis, the snow would collapse around large rocks. The first night, the winds were blowing in the 50-60 mph range with gusts well above that. I'm not a small man, and I was nearly knocked over a few times. It was calm after night 1. But there were many bare areas because of how the strong the winds were this year.
My guess - in two weeks - Anvil camp will be mostly melted out but you'll be hiking on snow up to the Pothole. From the Pothole, you'll cross a mix of rock and snow - more rock than snow. The pass will be holding snow for a while. It was very deep on the leeward side. Lookers left will be the best route up in my opinion.
Williamson Bowl was holding snow well. Lots of big drifts. We did see some new wet slide activity on the East faces of Versteeg and in that area. Lot's of ice and rock fall going on as early as 9:00 AM on the east facing slopes.
Two weeks is a long time off. Things will change considerably. But every time I took my skis off, I'd punch thigh deep into the snow. It did freeze at night. We could walk on the frozen snow easily until about 8:30 AM.
That was our experience. Hopefully it helps you. Have fun.
