We have received nearly a foot of new snow at upper mountain elevations in the last several days.

Yesterdays direct sunlight in the morning and partial sun in the afternoon accompanied by the diurnal fluctuation (day time warming do to the sun). Created quite a few point release size 1 slides along the Face of Mt Roberts and on Mt Juneau.

At 1pm as I was walking to lunch in downtown I notes a size 2 slide coming down Chop Gully on the town side of Mt Juneau. It looked like a very large all white waterfall for about 3 minutes. Impressive and fun to watch!

Larger slides like this can develope in open, steeper locations with longer slide paths.

Look to see snow falling off of trees, rocks, and cornices as well. This has the ability to start point release avalanches.

In steep open areas these relatively small slides have the ability to gather quite a bit of mass and momentum.

Look to see quite a few size 1 slides if the sun holds out long throughout the day. In areas with windloading and in pockets of additional mass larger class 2 slides are possible.

With the presence of Human Triggers backcountry danger is questionably high in areas.

Be sure to make good decisions and remember danger levels grow during the later heat of the day as the sun becomes more overhead and has more effect.

Remember, Partner, Probe, Avalanche Tranceiver, Shovel.
Dont leave home without them!!!
