This is why I don't agree with most zoos having exotic animals in the first place. Especially when the climate is so muh different.

Here's more info from the zoo
"Zoo officials argued that the benefits of moving Maggie were outweighed by its risks. They said that Maggie had a history of getting along poorly with other elephants and that she was easily made anxious by change. They reported that she had been "miserable and unusually aggressive" when Annabelle was still alive. Rather than moving her to a sanctuary, zoo officials decided to expand her elephant house, doubling its size, and to build the world's first elephant treadmill, a $100,000 elephant exercise machine which they hoped would help keep her healthy and in shape. Zoo director Tex Edwards said the Alaska Zoo would evaluate in three years whether Maggie's quality of life had been improved by the treadmill and renovations to the elephant house renovations and whether she should be moved from Alaska."

"Maggie's activities on mild winter days included taking "frequent romps in the snow." To keep Maggie occupied, Maggie interacts with handlers on a daily basis, and has opportunities for foraging and browsing. Her exhibit includes logs, barrels, and an "Enrichment Tree" designed by Delbert Cederberg of Allied Steel Construction, which has a street cleaner brush attachment for rubbing, arms for dangling objects like tires and stumps for Maggie to play with, and browse holders.[7] As of September 2006, Maggie had not been on the treadmill while it was moving, but was comfortable standing on and moving across it."
