While you may have heard that the January full moon is sometimes called the Wolf Moon, here in Denali we could call it the Sled Dog Moon. Turn up the audio to hear our sled dogs howl. Neither wolves nor sled dogs actually howl at the moon, but on dark cold January nights their voices sure can carry.

A chorus of sled dogs howl in the background. | Denali National Park a

It may be -40F out, but that doesn't keep the moose away! This is the same cow moose from yesterday that was poking around near park headquarters. She found a particularly tasty snack in this frozen willow tree. Amazingly enough, the 20 pounds of poplar, birch, and willow twigs moose eat on a daily basis allows for such a big mammal to survive the harsh winters of the cold North. | Denali National Park and Preserve
