Developed by the CAIC, the Avalanche Danger Rose is a quick, visual representation of the backcountry avalanche danger. The rose is not a map of danger in the zone. Instead, rose represents slope aspect and elevation, and the colors represent the danger ratings for those slopes and elevations. Imagine looking down on a cone-shaped mountain. On the Zone Forecast pages, clicking on the red question mark will run an animated demonstration of this. The 3-nested circles represent elevations. The outside ring represents terrain below treeline. The middle ring represents terrain at treeline, and the inside circle represents terrain above treeline. The colors follow the Avalanche Danger scale. Users should always read the accompanying text for additional information.
|This danger rose to the right represents the backcountry avalanche danger for all slopes below treeline at moderate. At treeline the danger on SW to W to NW aspects is also moderate; however, on N to E to S aspects the danger at treeline is considerable. Above treeline the danger on S to W to NW aspects is considerable. On N to E to SE aspects above treeline the danger is high.|
|This danger rose to the right shows a low danger with pockets of moderate for all slopes below treeline. The danger for all slopes at treeline is low. Above treeline the danger is moderate with pockets of considerable danger on N to E to SE aspects|
