Location: Corn Biscuit

Route & General Observations

We toured up Corn Biscuit today and found around 6″ of new, medium density snow
on top of the loose power and stellar crystals from the past few days. Winds
were redistributing the snow near, and slightly below, treeline. We did not get
above treeline due to lack of visibility and stormy weather.

Snowing around 1cm per hour with a north wind 5-15mph, below treeline. Snowfall
rates were picking up later in the day.

New snow was reactive and cracked easily on steep rollovers – not quite as easy
on less steep slopes. This occurred in areas without wind but was more prevalent
in areas where the wind was forming a soft slab on top of the loose snow. No
collapsing was felt.

Weak interfaces were both in the stellar crystals from yesterday (top of the old
snow) and in the bottom 2cm of today’s storm snow. See video for more details.

There was around 10-12 inches of new snow at the Motorized and Tincan parking
lots this afternoon, with a reported 14-16″ at treeline on the Tincan side of
the road.
