The Crystal Creek Pack is the largest pack of Yellowstone & Wolf Watcher First Attraction. They are highly visible on the Northeastern Entrance and interacts with a lot of animals.

Here is a quote from a staff member off the Greater Yellowstone Coalition on the topic of wolves in Yellowstone at the time :

"It was so pleasant last Saturday walking along in the Lamar Valley, knowing that at last here was a place with all the original predators and prey of prehistoric Yellowstone -- grizzly bears and black bears, cougar, wolves, coyotes, fox, badgers, bobcats, bison, elk, moose, deer, and antelope. Many of us have waited so long for this day."

The Pack makes an intrusion in the Hayden Valley Pack Territory and a brawl takes place. Both the dominant breeding wolves ["alphas"] of Hayden Valley, both very popular amongst tourists and wolfwatchers, wolves #540F & #541M are killed on this sad day.

540F was a lovely white wolf originating from the Nez Perce Pack while the light gray alpha male, wolf #541M, came from the Swan Lake Pack.

It must be noted that the daughter of 540F & 541M, the future "White Lady" [Canyon Alpha Female] was likely bred by a black Mollie's (?) interloper. This mating led to the birth of the only black pup of Hayden Valley in 2007, which would be collared as Wolf #638M later in its life.

The Pack chased the remaining Haydens out of the park in the next fews days [638M, 639M, "The Future White Lady", and some others].

Yearling #712M  & #587M would later joins with the Hayden female in 2008 to form the famous Canyon Pack.

Again, the Mollie's were not very popular amongst people. But, it is part of life.

Wolf #686F is one of the pups (she would be collared in 2009)

- July 2008 :

Wolves #587M & uncollared [but soon to be] #712M joined the Hayden Female before breeding season. And they had two pups sired by #712M.

Also "Limper" [the third male of the original Canyon Pack and the beta male] is possibly a born-Mollie's

- April 2009 :

Wolves #486F gave birth to her second litter of pups [5] with wolf #495M.

Their daughter, wolf #686F took the reins of the pack.

- December 2011 : 

The Pack had an encounter with the Mary Mountain Pack and killed their alpha male : #636M which originated from Cougar Creek. Nearly 3 year old 758M joined them and assume the alpha position.

- January 2012 :


Wolf #686F brings her pack of 19 wolves on the Northern Range [which they had not visit in over 2 years]. It was likely due to the absence of a mate.

- February 2012 :

"Big Brown" (778M), 693F, "Medium Gray" & another yearling of The Blacktail Deer Plateau Pack surprised and chased three of the black pups of the pack one morning.

778M, 693F & "Medium Gray" returned a few days later. This time, 9 mollie's attack the trio and killed the beta male "Medium Gray".

6 Mollie's were also in the vicinity of the scene

Also, a bunch of mollie's courted & flirted with #777M in august including #779F, #823F and others uncollared. Wolf #824M didn't like those interactions but didn't aggressively showed this.

However, one day, the other mollie's group, with 686F & returnee 3 year old #758M (who went lead the Mary Mountain Pack for a year) alongside at least 4 others dislike that and killed #777M on August 11th 2012
