‘They were mothers, wives, friends’: how a ski trip turned deadly in the California mountains

A picture is emerging of one of the worst avalanche disasters in US history, and the women among a tight-knit group of friends who died

The ringing of a phone echoed through the Nevada county, California, sheriff's office just before noon on 17 February.

The 911 call brought devastating news: an avalanche had occurred on nearby Castle Peak - a 9,110ft (2,780-meter) mountain north of the Donner summit in the Lake Tahoe area. A group of backcountry skiers had been on the mountainside, returning home from a three-day expedition, during a heavy winter storm. While six had survived, more than half their group was missing.
