Route & General Observations

Visibility was generally poor but was able to see mid elevations at times. It just seems like every time I am out and about I see new glide avalanches and cracks forming and/or growing. Today I saw a new glide crack north of the glide avalanche on Fresno. Fresno now has two glide cracks that have not released and one that has.

Looking up into Carter Lake I could see new bare ground from a fairly sizeable glide avalanche on Wrong Mountain just to the left of the one that came down two weeks ago. Clouds came in and pictures did not turn out good.

In the area of the school bus stop behind “avalanche acres” neighborhood S aspect of Moose Mountain South had a glide avalanche that reached the valley bottom.

Near Seward on Benson several wet slab avalanches came down on top of the glide avalanche from earlier in the week. Several smaller glide avalanches also came down. An additional 3 new glide cracks have formed as well in that area. With many additional large glide cracks growing on Mount Marathon above the trail into the bowl.

Look at mountains closely and avoid being underneath any of the many glide cracks out there!
