When Rhonda Miller spotted a dark figure recently on a remote stretch of highway in Canada, she sped for a closer look, thinking at first that it was a person.
But Miller, who otherwise had the road to herself, quickly became apprehensive when she realized there were two dark figures – and they were very large animals: wolves, spaced apart and running one after another, at full speed.
"My body immediately became afraid," she told CBC. "I was so struck by the size of their heads and their jaws."
At one point in her cell-phone footage, one of the canines glances toward Miller, as if angry about the intrusion.
The peculiar encounter occurred the snow-lined Yellowknife Highway in Edzo, Northwest Territories.
Miller’s only regret was that she did not check her speedometer to gauge how fast the wolves were running, but estimated their speed at 25 to 30 mph.
"So many men have asked, how fast were they going?" she told CBC. "Had I been a man I may have looked."
Gray wolves, whose winter coats are sometimes black, are the world's largest wild dog species. Males can attain weights of 150 pounds.
According to Canadian Geographic, gray wolves can attain running speeds of nearly 45 mph.
