You can easily trigger a large avalanche on steep, rocky, upper-elevation northwest, north, and east-facing slopes. Several feet of recent storm snow is overloading a very weak base. If you trigger a small avalanche in wind-drifted snow most likely it will break into deeper buried weak layers and grow in size quickly. Choose lower-angled wind-sheltered slopes to reduce your chances of triggering a large avalanche.
