I got out Thursday for a little outside social distancing time. In moderated terrain, with very talented skiers, close to our favorite heli base.... :)  Up 19 mile Creek. I've included a picture. In the top center you can see one slab cut out by a skier. Probably the day before. Moderate hand shear 25-35 cm down on a thin temp crust. Hazard is 2 at TL. 1 below.
Not sure about alpine but was getting windy with incoming wx. Prob 3
