I did not the mention of a beacon or sat com either.
That is even more surprising as many Youtube hiker and camper channels list devices like the Garmin inReach as an item they carry for every hike - even in good weather conditions and on frequented trails.
A device like that might have been of more benefit than matches. I carry BCB life boat matches. In a 60 mph snow storm I might still have trouble starting and maintaining a fire.
