Many slopes in the region are plagued by layers of weak faceted snow formed during the prolonged November dry spell. The persistent weak layer problem is a very dangerous and notoriously tricky avalanche problem, and it is responsible for most fatalities, injuries, and close calls in the Logan Zone. Avalanches failing on a persistent weak layer can be very sensitive, and they might be triggered remotely, from a distance, or worse from below!
