Slope Shape:
Whether a slope is concave, convex, or planar makes some difference
in avalanche danger, usually not a significant difference. Avalanches
happen on any steep slope without thick anchors despite the
shape of the slope. Slope shape makes more difference on smaller
slopes than on larger ones. |

Concave Slopes:
On small concave slopes, often there is enough compressive support
from the bottom to prevent hard-slabs from releasing but on
medium to large slopes, compressive support plays very little
role.
