American skier Lindsey Vonn says conditions were "too dangerous" to ski in at the women's World Cup meeting in Bansko, Bulgaria.
Fog caused two days of racing to be cancelled and there were delays on the third because of poor visibility.
Organisers ensured Sunday's super-combined went ahead, with Vonn starting when visibility was at its lowest.
"It's a joke, this snow is way too dangerous to ski," former Olympic champion Vonn, 30, said.
The American, who has only just returned to competitive skiing after two serious knee injuries, was 24th after the super-G and later declined to take part in the slalom part of the super-combined.
She posted a picture on her Instagram account on Sunday morning with the caption: "Ummmm.....The weather here is not wanting to cooperate... #whereamigoing #cantsee #notcool."
"I had to slow down all the way because I couldn't see a thing. The main thing is that I managed to go the finish without hurting myself," she added.
Germany's 2010 Olympic giant slalom champion Viktoria Rebensburg and Austria's Nicole Hosp also criticised the conditions.
"It was really difficult. The course was in a bad way, there were holes and the snow condition was a disaster. It was the case during the three days here," said Hosp, the 2007 overall World Cup winner.
"I cannot understand how this was allowed to happen," added the Austrian, who failed to finish Sunday's slalom run.
The super-combined was won by Austria's Anna Fenninger.
