'Protective' moose with calf tramples hiker in Colorado

Colorado wildlife authorities are reminding park visitors to keep their distance from wild animals after a moose trampled a hiker. 

On Tuesday, two hikers with three dogs, all on their leashes, spotted a cow moose and its calf near the Crags Trail, Colorado Parks and Wildlife said in a news release. 

The hikers said they were looking at the moose for some time and when they were done they tried to leave while maintaining distance from the animal but the moose kept moving closer to them, according to wildlife officials.
