Musk ox mothers stick close to their calves at the Musk Ox Farm in Palmer on Thursday, May 3, 2012. Twelve musk oxen have been born so far this season at the Musk Ox Farm. Staff at the farm are busy combing the animals to gather quviut which will be made into hats and scarves by Oomingmak, a cooperative of craftspeople. The Musk Ox Farm officially opens for the season on Mother's Day, May 13. Mothers are admitted free to the annual open house.
