LAKE LOUISE, Alberta (AP) – A ski gondola at Canada’s famed Lake Louise resort malfunctioned on Sunday, trapping about 65 people on board as darkness fell.

One of the safety switches on the Grizzly Express gondola tripped late Sunday afternoon, leaving the skiers stranded above the resort, said operations manager Rick Werner. Werner compared the malfunction to a flat tire and said officials were attempting to fix it.

There was no immediate word on injuries.

Eight teams of ski patrollers were working to evacuate the trapped passengers, who included children.
