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.

1289865600November 16, 2010 12:00Other Regions - Lips approach, 2200 ft.Snow profile at 2200 feet. This pit profile is typical of much of Turnagain right now. Mid and lower depths have surprisingly little of interest for early season. The recent wind slab at the surfac …
1289865600November 16, 2010 12:00Other Regions - CornbiscuitWe noticed these on the South face of Cornbiscuit. Take note of the ski tracks for scale.
1289779200November 15, 2010 12:00Other Regions - Tincan South FaceThis is a good example of how widespread the glide activity is right now. Full depth cracks and occasional avalanches are found on nearly every peak.
