Wolf 8M (Rose Creek Pack)

"Wolf #8M, another 1995 arrival, was found dead in Slough Creek in June 2000. He had aspirated water, but was in relatively shallow water, indicating he may have drowned after being injured by an elk. (It is common for elk to seek protection from wolves in water.) "

175F [Mollie's] (March 2003) (Killed by Bison)

"One of the prey-caused deaths was observed in Pelican Valley in March. A battle with a bull bison killed one of the Mollie’s pack wolves, and injured two others. The bison kicked one wolf, throwing it 10–15 m in the air, and hooked another with its horn, also launching the wolf airborne for several meters. The wolves eventually killed the bison, taking all of one day to do it. "

Wolf 296M (Agate Creek Pack) 

"One wolf from the Agate Creek pack [296M] died from apparent disease. Although we were able to retrieve the carcass from the field the day after discovering the mortality, disease analysis on the carcass was inconclusive because of slight tissue decay. Disease experts at the Montana Fish, Wildlife and Parks lab in Bozeman, Montana, had excluded other causes of death, and other evidence from the necropsy suggested death due to unknown disease. Prior to the necropsy in Bozeman, a field trip of visiting veterinarians inspected the carcass externally, and also corroborated a disease cause of death, based on bleeding from the anus and mouth."

Lab results confirmed he died of canine distemper virus and the virus in his particular case was concentrated in the nervous system"
