It was unclear how the walrus came to be so far from the water.
The calf was taken to a warehouse to spend the night and was transferred to the Alaska SeaLife Center in Seward the following day. Workers determined the walrus was dehydrated, malnourished and suffering from a cloudy eye. They said there is also the possibility of infection.
"Walruses are highly tactile and social animals, receiving near-constant care from their mothers during the first two years of life," the center said in a news release. "To emulate this maternal closeness, round-the-clock cuddling is being provided to ensure the calf remains calm and develops in a healthy manner."
The center said the walrus quickly adjusted and is feeding from a bottle.
A follow-up Facebook post said the calf was continuing to eat and appeared alert during the weekend.
