Observations

It is the personal responsibility of each user of CNFAIC to decide whether or how to use any information found here.

Skiing, snowboarding, snowmachining, hiking, walking, and all other methods of travel or recreation on snow are dangerous and a potential hazard to personal safety. Each person who ventures onto snow is responsible for his or her own safety. Many snow travelers find that education, information, and experience can increase their safety when they are on snow. The public observations reported on this site may appear to offer information about the safety of traveling or recreating on snow, but it is critical to remember that such observations are not evaluated or edited for accuracy and represent the subjective experience of the author.

Individuals may have widely differing perceptions, for a given location, date, and time, of the safety of traveling or recreating on snow, of avalanche hazards, and of skiing or snowboarding conditions. The hazards and conditions reported in an observation can change rapidly. In addition, individuals can differ greatly in both their perception of objective hazards and their acceptance of the risk to personal safety of these hazards.

1235520000February 25, 2009 12:00Outside of Advisory Area - SunburstI hiked above the rain crust zone to take a closer look at the new wind slabs/surface snow and how this snow is bonding to that old slippery hurricane layer. My compression tests found multiple mo …
1235433600February 24, 2009 12:00Outside of Advisory Area - Seattle RidgeThe Avalanche Center recently got some new snowmachines. They are super fun, and I reminded myself yesterday that I need to keep my human factors in check. Its easy to get excited about new gear …
1235433600February 24, 2009 12:00Outside of Advisory Area - Main BowlThis pit was at about 2400 feet in Main Bowl (again). Still finding failures above rain crust.
1235433600February 24, 2009 12:00Outside of Advisory Area - No Name Bowl/Zero Bowl/Mama'sThis is a North aspect in No Name Bowl/Zero Bowl/Mama's Bowl at 2700 feet. Not sure when this one happened, but saw it today 2/24.
1235433600February 24, 2009 12:00Outside of Advisory Area - Main Bowl Seattle RidgeThis is the 4th time I have dug in this location in Main Bowl. Previous dates were 11/21, 12/16, and 1/20. Amazingly the snow depth has not changed since 1/21. Compression tests didn't yield muc …
1235347200February 23, 2009 12:00Outside of Advisory Area - Middle Glacier Girdwood ValleyThis looks like a point-release wet slide might have triggered a slab avalanche around 2500 feet elevation.
1235174400February 21, 2009 12:00Outside of Advisory Area - Lipps SW AspectA skier triggered this avalanche on Friday 2/20 as he was skinning up the SW shoulder of Lipps at approx. 2500 feet elevation. The slab broke free 20-30 yards above him and carried him down the slo …
1235174400February 21, 2009 12:00Outside of Advisory Area - TincanStrong winds from sea level to the ridgetops on Friday 2/20 hammered the snowpack at Turnagain Pass. South and West aspects looked the worst. Protected areas below treeline still hold decent powd …
1235174400February 21, 2009 12:00Outside of Advisory Area - Tincan South AspectMost of the snow in Turnagain Pass is windhammered above treeline, especially on West and South aspects. Hard windslabs vary in thickness from 1" to 18" thick. Quick compression tests of the surf …
1235088000February 20, 2009 12:00Outside of Advisory Area - AlyeskaAlyeska Ski Patrol confirmed the weak layer from Tuesday's (2/17/09) artillery-triggered avalanches on the outer area of the Alyeska's North Face called the "Money's. The facets on top of the Janua …
1235088000February 20, 2009 12:00Outside of Advisory Area - Skookum ValleyThis natural avalanche probably occured on Sunday or Monday 2/15 or 2/16. We just saw this one today 2/20. It's at the right elevation for the rain crust/facet weak layer. Be extra careful at th …
1235001600February 19, 2009 12:00Outside of Advisory Area - Main BowlCompare this pit to the pit from 2/10/2009. My main concern with this pit are the facets on top of the rain crust. If Turnagain Pass ever gets a load like Girdwood did last weekend, then this wil …
1234915200February 18, 2009 12:00Outside of Advisory Area - Upper Girdwood ValleyCPG intentionaly ski cut this avalanche at about 4500 feet on a WSW aspect on A-1 glacier. They found some sensitive slabs failing under their skis when they increased their slope angles above 30 …
1234915200February 18, 2009 12:00Outside of Advisory Area - TincanThis skier-triggered avalanche happened sometime between 4pm yesterday and 1:30 pm today (2/18/09). It is on a western aspect at about 2800 feet. A similar elevation band as the natural avalanche …
1234915200February 18, 2009 12:00Outside of Advisory Area - Peterson CreekThese natural avalanches at about 1800 feet on steep terrain probably avalanched during Sunday night or Monday morning.
1234915200February 18, 2009 12:00Outside of Advisory Area - Alyeska North FaceThe "Moneys" is an outer area on the North Face of Alyeska. This picture shows how artillery ripped out avalanches across the entire face of this slope.
1234828800February 17, 2009 12:00Outside of Advisory Area - Eddy'sThis natural avalanche on the WSW aspect of Eddies probably ripped out on Monday 2/16/2009. Natural avalanches can be indicators that the snowpack is losing its tolerance for extra weight.
1234828800February 17, 2009 12:00Outside of Advisory Area - TincanThis natural avalanche on the north side of Tincan near CFR probably occured on Monday 2/16/2009. It not very big, but we have not seen natural avalanches in the upside down surface snow until thi …
1234828800February 17, 2009 12:00Outside of Advisory Area - Byron Glacier ValleyThis is a poor quality photo, but its worth showing that deep crown face we saw out in Portage Valley. I'm guessing that the crown face is at least 15 feet deep. This avalanche probably ripped ou …
1234828800February 17, 2009 12:00Outside of Advisory Area - WolverineHere is another clue that the rain crust at lower elevations is a dangerous weak layer. That rain crust extends from sea-level to about 3000 feet. We have been finding facets above and below this …
1234742400February 16, 2009 12:00Outside of Advisory Area - Silvertip CreekThis slab avalanche was triggered remotely by the skier in the photo. It was 12-16 inches deep, ran 150-200 feet around the next ridge to the left.
1234569600February 14, 2009 12:00Outside of Advisory Area - Sunburst SW AspectThis pit was located on a SW aspect at 2300 feet not far from the skintrack. The snowpack was fairly shallow at this location...only 3.5 feet to the ground. We got moderate Q2 and Q3 shears below …
1234224000February 10, 2009 12:00Outside of Advisory Area - Main BowlThere is a bad temperature gradient above the top crust. We saw rounds turning into facets in the snow above that crust, and that is also where the stability tests showed the most action. Crusts …
1234137600February 9, 2009 12:00Outside of Advisory Area - Pyramid
1234137600February 9, 2009 12:00Outside of Advisory Area - Tincan SW aspect240 cm to ground. Pit located at 3170 feet on a SW aspect. Moderate to hard Q2 shears on pineapple express layer 1.5 feet down. No propagations during extended column test.
