More detailed information about the weather

We left the parking lot under cloudy skies and could see sun hitting Todd ridge occasionally on our skin up the west side of Tumalo. We noted windpacked snow of varying depth over a hard rain crust. When we reached the summit around 10:20 AM the skies cleared briefly and we had good visibility for our run down. The far lookers right side of the bowl had decent coverage, with about 6 inches of dense windpack on top of the icy layer. The north side of the butte was a different story, with wind-scoured ice making for a tricky traverse on our way back to the west side. There was no blowing snow, but snow conditions indicated that certain areas could be quite wind loaded.

More detailed information about the avalanche

While touring at Tumalo Sunday morning we observed a very recent slide on the E/SE aspect of the rocky ridge on the lower, lookers right side of the bowl. What appeared to be a wide, wind-loaded slab (R5D1) released, leaving a 1-2ft crown along the entire ridge. After skiing the far lookers right side of the upper bowl, we went to check out the debris but didn't go up to the crown since weather was moving in. We observed recent ski tracks coming out from the bottom left side of the debris.
