The Northern Rocky Mountains wolf (''Canis lupus irremotus''〔), also known as the Northern Rocky Mountain wolf, is a possible subspecies of gray wolf native to the northern Rocky Mountains and the high adjoining plains, from northwestern Wyoming northward through western Montana and eastern Idaho at least to Lethbridge in southern Alberta. It is a light-colored, medium to large-sized subspecies with a narrow, flattened frontal bone.〔Glover, A. (1942), (''Extinct and vanishing mammals of the western hemisphere, with the marine species of all the oceans'' ), American Committee for International Wild Life Protection, pp. 205-206.〕 The subspecies was initially listed as Endangered on March 9, 1978, but had the classification removed in the year 2000 due to the effects of the ''Northern Rocky Mountain Wolf Recovery Plan''. On August 6, 2010, the Northern Rocky Mountains wolf was ordered to be returned under Endangered Species Act protections by U.S. District Judge Donald Molloy in a decision overturning a previous ruling by the U.S. Fish and Wildlife Service. They were later removed on August 31, 2012 from the list because of Idaho, Montana, and Wyoming meeting the population quotas for the species to be considered stable.〔 , it is considered a valid subspecies by MSW3, though it is classed as a synonym of ''C. l. nubilus'' by the United States Fish and Wildlife Service. ==Physiology==
