. Further surveys by the end of 2012 showed a count of at least seven wolves in a pack within the Upper Minam River area. The Oregon Department of Fish and Wildlife reported in 2013 a total of six known packs with 46 total wolves. All animals belonged to the same pack and are designated ''Minam Pack''. The first grey wolf trapped and radio-collared tagged by the ODFW was an female individual and marks the twentieth radio-collared wolf in Oregon. Another female was radio-collared which dispersed from the Miniam Pack and found traveling with another male wolf within the Miniam Area and into the Keating Unit. Through 2019 the Minam Pack produced litters annually within the Eagle Cap Wilderness. One of the females from the Minam Pack formed a pair bond in 2014 with a male member of the Snake River Pack forming a new pack within the Eagle Cap Wilderness, designated the ''Catherine Pack''. The adult female was found deceased in 2019 although the pack remained classified as a breeding pack through 2019.
