The Aspect/Elevation diagram describes the spatial pattern of the Avalanche Problem by aspect (the direction a slope faces) and elevation band (Above, Near, or Below Treeline). The diagram will be filled with gray where you are most likely to encounter the Avalanche Problem . You can view the diagram as you would a mountain on a topographic map. The outer ring represents the Below Treeline elevation band, middle ring Near Treeline, and the inner ring Above Treeline. The diagram is oriented like a compass, with the top wedges representing north aspects, the left wedges representing west, etc.
