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. [Updated 4/2017]
