Written Report:
Mt Thielsen's SW bowl skied amazing yesterday afternoon. Despite the rapid rise in temperatures, there was no evidence of loose wet activity on 4/11.

On a W aspect there was debris from a wet loose avalanche from last week's warm temps, as well as some truly giant pinwheels. Certainly the potential for small slides as this week warms.

I could also hear water percolating in the snow pack in shallow areas near exposed talus in the upper portions of the SW bowl. I descended at 3:00 PM and the corn was perfect all the way into the treeline.
