Written Report:
We toured up to Tumalo Mountain and took a few laps in the bowl. Conditions felt very stable and the snow seemed to be bonding well to the previous week's deep ice crust. We did not dig a pit because it would likely have been impossible but did not many pole tests on the tour up as well as randomly in the bowl - all were consistent with 6-12 inches of snow on an impenetrable crust.
On one run, we skied the really short but relatively steep section below the large rock outcropping on skiers left nearing the bottom of the normal route. There, we both kicked off sloughs that did run surprisingly easily. When we did some pole tests around that area, there was a second, very fragile crust which seemed to be the culprit. In check some more on the climb out we found more evidence of this weak crust layer in the far skiers left side of the bowl - where you normally skin up.
Over all - much better snow than expected but odd to find that layer.
