Observer Comments

Loose snow avalanches and roller balls predominately 2500' and below. There were a few that initiated closer to 3000'. Recent glide avalanches and glide crack growth.

There was a loose snow avalanche on Sunburst that looked like it initiated just below the main cornice.
Glide cracks on the West face of Magnum and Cornbiscuit. Almost all the skinnable terrain on Cornbiscuit is now threatened. The mini glide on Sunburst is growing. The Magnum cornice is hanging tough and still looking ominous. There is a growing glide crack on the PMS bowl usual up-track.

The major instabilities have be confined to the 1000'-2500' elevation band. It appears that if the temperatures stay warm they may creep into the Alpine…

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.
Weather

Rain sprinkles and a few random snowflakes
Partly cloudy with periods of strong sunshine
Temps in the high 20s at 3000'
Winds were light and easterly

Snow surface

1000'-2000' wet saturated snow
2000'-2500' 4-6" wet-moist snow over a crust
2500'-3300' 2-4" moist snow over slightly drier snow on North aspects and over mf crust on Southerly

Overall the moisture content in the snowpack has increased throughout the week and the saturation line is going higher. There was evidence on rain on snow to about 2300'. The skin track to Todd's from Wednesday was not evident. 5-15 cm of new snow and wind over the past few days covered it over.

Snowpack

Dug at 3300' on a North aspect, 30 degree slope. Dug 100 cm down. Nothing remarkable. 65 cm of moist-dry right side up snow over the 3/25 crust. No significant stability test results. 10 cm of new snow from the past couple days. No cracking along the ridge or indication of reactive wind slab.
