Aspen

You can easily trigger a small avalanche in the new snow on most slopes, and in wind-drifted areas at upper elevations along the leeward side of a ridge, they can grow large enough to bury you. You might be able to trigger a larger and deadly avalanche on deeper weak layers on rocky, shallow, north-facing slopes above treeline. To reduce your chances of being caught in an avalanche, avoid high-elevation, thin, rocky slopes facing towards the north and identify and avoid steep, wind-drifted slopes.
