For the second time in less than a week, rescuers have been called out to help people who went out of bounds in a B.C. ski area.

In the latest case, a father and his three teenage sons, who were visiting from Sweden, got lost Wednesday after passing under a rope and leaving the marked ski area of the Revelstoke Mountain Resort, east of Kamloops.

RCMP Const. Dan Moskaluk says the father used his cellphone to alert authorities that his group was stuck in an area just east of the resort.

He says a search and rescue helicopter found the group and dropped supplies to them but was not able to get them out because of the weather and the approaching darkness.

Moskaluk says the group was forced to spend the night on the mountain until rescuers are able to return.

The four skiers were rescued Thursday morning at around 8 a.m. from the Montana Creek area without any complication. The skiers did not need any medical attention.

On Tuesday, a snowboarder was rescued from the wilderness near West Vancouver after being stranded for two days after he went out of bounds at the Cypress Mountain resort.
