Heavy fog in a remote area of British Columbia is preventing investigators from reaching the site of an avalanche that killed seven skiers Monday.
Three of the dead were Americans. One was a 49-year-old Littleton man. The two others were from California.
All were part of a group brought into the remote area by helicopter.
One other skier was hospitalized after yesterday's avalanche. Survivors spent the night at a remote chalet. It's not clear yet how they'll be evacuated.
Avalanche conditions in the area had been rated as hazardous Monday.
