In a perfect world yes. Their are so many factors to be considered. How fast was new snow piling up? What was the historical stability of that area relative to an avalanche? What were current temperatures, new snow forcasts etc. etc. etc.
This could have been easily prevented by denying skiing totally which is idiocy. Those skiers know the risks and accept it for the joy of their sport which they know might kill them. I am a pilot that can no longer fly due to medical conditions. I was commercial and a flight instructor but my real job was oilfield, geology and lastly pharmacy. I did mild aerobatics and one that was extreme. The extreme was what we called a "beat up" in England where I learned to fly and in the USA a "fast pass." In a glider, no engine.
One would be on finals at about 600 feet and dive at the ground to your landing point and level out at VNE (velocity never exceed least you have structural failure). You did this down wind thus your velocity over the ground would be about 150 knots, your whole world was just a few degrees in front of you and all else just a blur in your preferential vision. You must then convert all the energy and speed into altitude via a chandelier and land. When you landed the feeling was incredible. I felt totally alive though I was an old man that now can not fly. That is why I will not criticize those skiers. They knew the dangers in their sport as I did mine. We both accepted the risks. My risks were greater than theirs. I got lucky, they did not.
I took unnecessary risks a few times (when my parents weren’t home) as an 18/19 year old, flying the Tri-Pacer between the pasture trees, mimicking George Peppard’s dogfight in the trees, in the Blue Max.
Self taught a few aerobatics. Foolish, but both me and the plane survived unharmed. Had a lot of fun flying out of that farm strip over 50 years ago, in central Suez township, Mercer County, IL
To paraphrase Eric Clapton: dopamine is a heck of a natural drug.
And so is pride. (Both have effectively killed many)
