**Special Note:  Please be careful if you head into the backcountry after this snowfall.  It’s been a mess out there with literally hundreds of people skiing the same zones with major lack of avalanche etiquette. 

A skier was partially buried in an avalanche near Kirkwood on Wednesday after taking a 150-foot ride.
