Obvious signs of instability, such as cracking and collapsing in the snowpack, have diminished, but you can trigger a large avalanche deep in the snowpack with little warning. Steep northerly and easterly slopes are the most dangerous. You can trigger an avalanche from a distance and from below. Avoid trigger points like trees and exposed rocks where weak layers are easier to collapse. You can find safer travel on terrain less than about 30 degrees that does not connect to steeper slopes and in areas without a buried weak layer.
