HELENA, Mont. — A wild wolf known as 926F, dear to the hearts of wolf watchers who visit Yellowstone, was killed by a hunter as it wandered just outside the park last weekend.

A member of the Lamar Canyon pack in the national park’s northeast region, 926F was the daughter of 832F, an alpha female that had become a celebrity, famous for her hunting prowess and for her frequent appearances along the road traveled by tourists in the park’s Lamar Valley.

While wolf biologists called the mother 832F, the she-wolf was famously known as “06” for the year she was born. The subject of the book “American Wolf: A True Story of Survival and Obsession in the West,” she was killed by a hunter as well.

“Everybody’s mourning, everybody’s thinking about what to do to stop this madness,” said Karol Miller, who founded a group of wolf lovers on Facebook called The 06 Legacy. “People love the Lamar Canyon Pack and people know 06 from her New York Times obituary. These are the descendants of 06, her legacy. People love those wolves.”
