Summary

Problems

Loose Dry

An icon showing Loose Dry
Periods of intense solar warming on steep slopes facing the sun could produce small loose avalanches. If the sky clears in the afternoon, limit your exposure to this solar effected terrain and rocky outcrops which will be warming up.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Expected Size

2 - 4

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Unlikely
