On Wednesday, a separate, massive avalanche was triggered outside the marked tracks in the same location near the Col de Gentianes on the Nendaz side. It was between 300 and 400 meters wide and triggered an extensive search and rescue effort involving eight rescue helicopters and several search dogs. It was unclear at the time how many people may have been buried in the snow. At one stage, it was believed that up to ten skiers were in the avalanche, but apparently, all could free themselves and did not require medical assistance. Unfortunately, the extended search and rescue efforts found a Russian skier, aged 58, for whom all help came too late, and he was declared dead at the scene.

The enormous size of Wednesday’s fatal avalanche can be seen in comparison to Monday’s picture.
The avalanche danger in the Swiss Alps may last for a few days. On Tuesday, the threat of avalanches in all of the Valais Alps was still high, at Level 4 out of 5. It returned to Level 3 on Wednesday when the larger avalanche was triggered.
"The situation remains tense and dangerous; be very careful," wrote the Institute for the Study of Snow and Avalanches (WSL) on Twitter.
