The 27-year-old skier, a woman from Barcelona, died on Wednesday while going off-piste alone in the Soldeu resort in Andorra, in the Pyrenees mountains between France and Spain, a resort manager told news agency AFP.
Although she was rescued within 10 minutes, after her glove was spotted on the surface, she was unable to be revived despite a helicopter dash to hospital.
In similar news, in the Italian Alps, close to the border with France, a 24-year-old Frenchman who was snowboarding with three friends on a closed run died on Thursday when an avalanche swept over him in the resort town of Les Arnauds.
Local officials said he succumbed to multiple injuries, asphyxia and hypothermia.
Avalanches are common in Europe's ski resorts at this time of year, when early snows are heavy with moisture, and several deaths occur each winter.
Last Sunday, a 35-year-old Frenchman died in an avalanche in the Alps near the Italian border while on a three-day trek with a friend.
