Wolverine Bowl Avalanche Wolverine Bowl Avalanche -Feb 21, 2015

"Triggered two small avalanches in wolverine bowl today. One started from sluff we kicked off while descending from the ramp into the bowl. The second was triggered by my friend on a 40 degree SE convex slope. The crown was no deeper then 1 ft, but it broke over 150ft wide. Not enough debris to be scary, but with another foot of snowfall I would worry. Both slides broke on a soft crust at the new/old interface." Photo: P. Dixon
