All reigns, no matter how historic, ultimately come to an end. And according to officials, Yellowstone National Park ’s “Queen of the Wolves” finally passed away at 11-years-old after succumbing to wounds from a fight.

One of Yellowstone National Park’s oldest gray wolves, a one-eyed matriarch dubbed 907F, has died after sustaining wounds in a fight with a rival pack. Affectionately named “queen of the wolves”, 907F lived to the grand age of 11 – exceptionally long for a wild canid – and birthed an astonishing 10 litters in her time.

The collar on 907F, one of the best-known gray wolves in Yellowstone National Park, signaled "mortality" last week—indicating the matriarch of the Junction Butte pack had died of injuries suffered in a fight at age 11.
