Yellowstone's wolf packs—Wapiti Lake Pack

The Wapiti Lake Pack was founded by 755M in 2014. In reality, 755M had been traveling around much of the Northern Range, not joining a pack or finding a mate for about 2 years. This former alpha male of Lamar Canyon Pack returned to the Park in winter 2012 from a trip east and joined up with 759F from Mollie's Pack, who later left him. After being alone for a few months, 755M was seen with an uncollared gray female in April 2013, then later with 889F. 755M appeared to have joined Junction Butte, but split off with 889F in 2014. The pair spent time in the Hellroaring area before 889F was harvested outside of the Park. Finally, in 2015, 755M settled down in Hayden Valley with an uncollared gray female where they denned and had pups. Mollie's wolves joined the small pack in 2016 and 755M was seen in numerous places around the Northern Range and potentially joined the Beartooth Pack by 2017. In 2017, the famous White Alpha Female's daughter (similarly colored to her mother), became alpha of Wapiti Lake pack. Both 1091F and the White Female had litters in 2017 (to the best of our knowledge, one of the few packs that did). Visitors enjoyed watching this pack at their Hayden Valley den site. 3 or more males from the Wapiti Lake pack split off and joined 8 Mile in winter 2018/2019. The main Wapiti group, including 1014M and the White Female, remained in the Hayden and Norris area throughout the winter. [Updated 04/2019]

Past pack members

ID Social status Age class Color Sex Age Mange status Birth year Birth pack Death year Description
755MUnknownBlackMale11Uninfected2008This black wolf is turning gray, so he is often mistaken as a gray wolf. He has travelled widely for years, joining new packs or forming his own. He founded the Wapiti Lake Pack in 2015 with an uncollared gray female. He may have joined the Beartooth Pack in late 2016.
1015MAlphaUnknownBlackMale5Infected2014Mollie's PackDispersed from Mollie's to Wapiti Lake Pack in 2016. Then, left Wapiti Lake in the winter 2018/2019 to become the alpha male of 8 Mile, thereby replacing 962M. A small mange patch was noticed in March 2019 on the top of his neck behind his ears.
1091FSubordinateUnknownGrayFemale4Uninfected2015Wapiti Lake Pack20181091F, or 'mouse' for her mouse hunting activities, died in early January 2018. We suspect she was injured during a hunt, likely by a bison.
