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.

1238889600April 5, 2009 12:00Turnagain - CornbiscuitThis natural avalanche on the north and west aspects of Cornbiscuit happened on Friday, April 3. It slid on the January rain crust.

1238198400March 28, 2009 12:00Outside of Advisory Area - Pete's NorthThis natural on the southwest face of Pete's North occurred sometime after the storm on Wednesday 3/25.
1238112000March 27, 2009 12:00Outside of Advisory Area - Lower Turnagain PassThis is only part of this particular avalanche. My other photo is zoomed out, but the flat light made it difficult to see the crown face. This avalanche probably 1 mile wide.
1238112000March 27, 2009 12:00Outside of Advisory Area - Seattle Ridge (Repeat OffenderIt looks like this slab avalanched earlier during the storm because it is filled in, and its difficult to see the debris pile. It good that a big chunck of the snow hangin above the snowmachine up …
1238112000March 27, 2009 12:00Outside of Advisory Area - Eddy'sThis avalanche occured at about 2800 feet. That is well within the January "Hurricane" rain crust elevation.
1238112000March 27, 2009 12:00Outside of Advisory Area - SunburstSimilar location to the avalanche that occured on Sunday 3/22/09. We dug a crown profile and confirmed the failure layer was the facets on top of the January "Hurricane" rain crust, just like we h …
1238112000March 27, 2009 12:00Outside of Advisory Area - TincanThis avalanche occured on the southern aspect of Tincan. The clouds and flat light made it difficult to see, but there were also large avalanches on the northern aspect. The bottom of Todd's Run …
1238112000March 27, 2009 12:00Outside of Advisory Area - Max's SW FaceTake your pick of weak layer. This avalanche stepped down and around to several different layers.
1237852800March 24, 2009 12:00Outside of Advisory Area - SunburstWe saw this small avalanche on Tuesday 3/24/2009. This avalanche is still big enough to knock you over, take you for a ride, and bury you if there is a terrain trap at the bottom. We are not exac …
1237852800March 24, 2009 12:00Outside of Advisory Area - Tincan NW AspectThis avalanche occurred at 1800 feet on a northwest aspect of Tincan not far from the skin track. We're guessing it occurred sometime Sunday 3/22. It failed on the buried surface hoar that formed …
1237680000March 22, 2009 12:00Outside of Advisory Area - unknownThis avalanche was remotely triggered on Sunday 3/22 by some folks digging a snowpit a short distance away. The slope angle was estimated to be in the low 30's. The avalanche occured on a west as …
1237593600March 21, 2009 12:00Turnagain - Cornbiscuit South AspectThis small avalanche (potentially skier triggered within the past few days) was observed while skinning up Bertha Creek. Starting elevation ~3200', ~30-40' wide, slid ~600' nearly to the valley. T …
1237507200March 20, 2009 12:00Outside of Advisory Area - Warm Up Bowl Ridge (zero bowl
1237507200March 20, 2009 12:00Outside of Advisory Area - Warm Up BowlThis sun crust had surface hoar on top, and a very bad temperature gradient underneath which creates facets. It was already super fragile underneath.
1237507200March 20, 2009 12:00Outside of Advisory Area - Main BowlStill finding hard failure in facets slightly above January Hurricane rain crust. I also saw a layer of very decomposed buried surface hoar at about 1.5 feet (55 cm) deep where the failure occured …
1237507200March 20, 2009 12:00Outside of Advisory Area - Warm Up BowlSun crust was about 1 inch thick and it broke very easily underneath. It already has very bad temperature gradient which will most likely grow facets underneath. Plus, there is surface hoar on to …
1237507200March 20, 2009 12:00Outside of Advisory Area - Bartlett GlacierNot sure when this natural avalanche happened, but I'm guessing at the tail end of the St. Paddy's Day storm based on the clean fracture line.
1237507200March 20, 2009 12:00Turnagain - Magnum West Aspect 1800'
1237507200March 20, 2009 12:00Outside of Advisory Area - A-1 SE AspectThe trigger was a skier "body-bomb". This happened around 2500' elevation on a SE aspect in the upper Winner Creek drainage.
1237507200March 20, 2009 12:00Outside of Advisory Area - Max's SW AspectI dug this snowpit at 2400 feet on a SW aspect. The total snowpack depth at this spot was only 4.5 feet. I got moderate Q2 shears on the facets above the January rain crust (16" down) and underne …
1237334400March 18, 2009 12:00Outside of Advisory Area - North Bench PeakThis avalanche was ski-cut and described as 3 feet deep and about 200 feet wide. It sounds like this was new storm snow that failed on the "glazed donut" layer. Thats the thin freezing rain crust …
1237334400March 18, 2009 12:00Outside of Advisory Area - Twin PeaksWe saw this natural avalanche on Wednesday 3/18/09. The crown face still looks clean enough that I'm guessing it ripped out sometime Tuesday 3/17/09. I'm also guessing that this failed on the "gl …
