Snow level was near 5,000 feet, and big wet snowflakes were observed at the bottom of the Grey Butte skin track. Slightly less than an inch per hour was falling from the sky with occasional flurries of heavier snowfall. Moderate southerly winds were loading north and easterly aspects. A total snow depth of 35 inches (90 cm) with 8 inches (20 cm) of new snow was measured at the beacon checker at 6,700 feet.
The new snow was heavy but began to feel lighter as we toured toward higher elevations on the butte. Many bushes protruded from our shallow snowpack and were barely covered by the new snow. Skies cleared briefly after 1 p.m. We observed minor cracking and blocking on small test slopes along the skin track. An average snow depth of 45 inches (115 cm) with 10 inches (30 cm) of fresh snow was measured along the ridge top of Grey Butte. Drifts up to 2 feet deep have formed along the easterly side of the ridge. Test slopes were stubborn and generally unreactive to stomping. This may change if we receive more wind.
