Video Of Ski Bros Rescuing Guy Buried Alive After Spotting His Skis Sticking Out Of Snow

Was there an avalanche that pinned him. I'm not understanding how is stuck if he just fell into a deep spot. I know an avalanche packs you in. this had to be after an avalanche. That guy is some kind of lucky

glad they rescued that guy, but I assume he was skiing alone? Can never do that in that type of area that clearly is off-slope with waist high snow.
