A storm caused a a power surge, knocking out power on Jasper's famed SkyTram and causing 160 people to be stranded on top of Whistlers Mountain. 

Parks Canada used a helicopter to bring people down in small groups. As dusk approached, rescue officials knew they couldn’t get everyone down the mountain. SkyTram general manager Todd Noble took the last flight up and stayed overnight with about 50 stranded travelers.

Everyone was back down the mountain by 10:30 a.m.Tuesday. No one was injured.

The tram will be closed until Thursday.

Jasper SkyTram will review its action plan in case something similar happens again.
