Expedition Everest at Disney's Animal Kingdom is currently undergoing some refurbishment work.
The park's signature attraction is still open to guests as normal, but the rear of the mountain has scaffolding in position, along with a crane. It is not clear what the extent of the refurbishment is, but so far, the broken track at the top of the mountain has been removed, and the bird effect has been reinstated.
The attractions main effect, the animatronic yeti, has not worked since late 2007, around a year after the ride opened. If anything will be done to this show scene during this refurbishment is yet to be seen.
The broken track prop seen here is currently removed
