Most of the packs have radio collared wolves in them making them trackable. "The Sherman pack was confirmed in the spring of 2016 after winter surveys documented that the collared wolf that had served as the breeding female for the Profanity Peak pack during 2015 had dispersed, paired with an unknown male,and were traveling together during winter, thereby forming a new pack in an adjacent area. WDFW collared that male on February 16,2016 using a helicopter. The Sherman pack produced pups in the spring of 2016, " "Sherman Wolf Pack: 2017 Lethal removal action" https://wdfw.wa.gov/publications/01949 https://wdfw.wa.gov/publications/01949
