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.
