Written Report:
Lately the overnight low temperatures have been slightly above freezing, and last night they barely dipped below freezing (31 F for an hour last night at our Moon Mt station). The surface snow has still been freezing, and I found good corn skiing on the Hayden and Diller Glaciers. I was surprised not to see much recent Loose Wet debris. The Loose Wet avalanches that I saw were mostly the same ones I saw on North Sister on Sunday. There were recent Cornice Collapses (see picture 1 of a moraine feature). Pretty much anywhere I've scene a cornice there is some sort of debris beneath. The sky was clear all day, and the wind was mostly Calm and occasionally Light from the North. The high point of my ski was 8610 ft. and at 11:50 it was 3 degrees C there.

Now that spring is here, and I'm more often looking at weather stations for temperature info than for snowfall totals I've been finding our Moon Mt. Station particularly useful: https://www.wunderground.com/dashboard/pws/KORBEND177
