Written Report:
I toured up Tumalo today to see whether the forecast of snow and moderate/strong winds would come to fruition. Today, it seems, the forecast was spot on.

Snow was falling lightly through most of the day, stacking up another few inches on top of the 4 in. that fell overnight last night. It was enough to cover up the very stout crust and make for some nice skiing in the trees and open glades.

Up higher was a different story. Strong westerly winds were moving snow around quite a bit, blowing sideways snow, scouring surfaces, and building large drifts.

Around midday, the sun made a brief appearance and I hoped to catch a glimpse into the bowl. I could see wind transporting snow into the bowl and developing large drifts/cornices. Then the clouds moved back in and everything whited out. See pics below.

I skied down the north side and dug a pit on an east aspect at 7238', where I was a bit more sheltered from the wind. Key takeaways: I measured about 22 cm of light, unconsolidated snow over a stout crust. Below, I found layers upon layers of crusts. Total height of snow in this location was 300 cm. See attached profile for details.

As I toured out, the clouds began to break up and I was able to catch a few glimpses of the bowl from below. I did not see any avalanche activity.
