DEF

The compass direction a slope faces.

CONT

Slope Orientation. The orientation of the slope to the wind and sun is critical. Leeward slopes (facing away from the prevailing wind) are rapidly loaded by heavy snowfall, even during periods of clear weather. ... The slope's orientation to the sun is also important. South-facing slopes receive the greatest amount of incoming solar radiation and tend to stabilize more quickly, but they may also release as a wet slide when the sun warms them.

CONT

Natural and accidental avalanches were reported this week in various areas on steep slopes, in particular, on south and east aspect. [Example approved by the Avalanche Bulletin Terminology Standardization Committee.]

OBS

For example, a slope on the east side of a mountain has an east aspect.
