Vancouver ended its time hosting the 2010 Olympic games on a light-hearted note, with a closing ceremony that featured floating moose, dancing Mounties and gigantic cut-out hockey players wearing the gold medals Team Canada had won hours before.

The upbeat ending was in stark contrast to the grim beginning of these games, which were marred by protests, the death of a Georgian luger, and then by unseasonably warm weather that left organizers postponing events and trucking in snow on Cypress Mountain.

``You took on a stubborn mountain with all your might,'' said Vancouver Organizing Committee CEO John Furlong, lauding the games' blue-garbed staff in a speech during the ceremony. ``The final result: Blue Jackets 1; Cypress Mountain weather zero.''

During the closing ceremony, Vancouver passed the baton to Sochi, Russia, which will host the 2014 winter games.
