We don’t know much more about this than this video shows.
“This is the full video of Christian getting caught in an avalanche. January 15, 2016.” – Christian Mares
We do know that this occurred while Lake Tahoe was under an Avalanche Warning and that this avalanche happened the day after a Sugar Bowl ski instructor went missing at or around Sugar Bowl ski resort in CA. That person is still missing.
Stay safe out there.
