Grizzly Gulch, Silver Fork, Days Fork, Cardiff Fork, Mineral Fork

Elevations, slope angles and aspects

7000-10400', angles over 35°, all aspects.

Snow conditions

I found 4-10" of new snow. Snow flurries during the day added...not much.

The snow was right side up and well bonded to the old surface.


Scattered, isolated collapsing on a couple of small wind drifts formed during the high wind-dense snow period early in the storm.

Scouring was on, primarily, west facing aspects, mostly near ridges.

Lee aspects had less wind effect with the old surface rarely felt on the down.

Lower elevations had less new snow which was still dry in the afternoon, a little crunchy.


Overcast with patches of blue early in the day.

Clouds increased, visibility diminished and snow flurries developed as the day progressed.

Winds were light, moderate temperatures.

Avalanche activity

None observed.


Good stability in the area traveled.

Future instability would be from increased wind or rapid warming.
