Backcountry enthusiasts continue to trigger large avalanches without warning signs like cracking or collapsing. Natural avalanches have also been reported. Increased wind and snow should continue this activity. Many tracks are on steep slopes but don’t assume this means a slope is safe as you may find a weak spot in the slab. Wind-drifted areas are the places you are most likely to trigger an avalanche, but there is a good chance these will step down to deeper weak layers. Thin rocky slopes are the most dangerous. You can find safer travel on slopes less than about 30 degrees without steep terrain above.
