A woman was trampled by a cow moose on her property in Nikiski on Monday morning, according to a dispatch from the Alaska State Troopers.

The moose had been on Crystal Cook’s property for a few days before witnesses later noticed a newborn calf. Some of Cook’s neighbors said the cow moose was observing her calf from the other side of the fence, according to the dispatch.

After the calf “called the cow in tones of distress,” witnesses said they saw Cook encroach on the newborn’s space. As Cook moved closer to the calf the cow moose jumped the fence, knocked Cook to the ground and trampled her, troopers reported.

According to the trooper dispatch, neither the moose nor the calf have been located.

Paramedics treated Cook’s injuries on the scene of the trampling before she was transported to an Anchorage hospital for further treatment.

“As a reminder, as calving season is fully underway throughout much of Alaska, never approach a calf moose or come between a cow and calf moose, as a cow moose will typically respond with aggressive actions if it fears for the safety of the calf,” the dispatch stated.
