This is a nice picture of an opinion. Where’s the radio collar data supporting these migrations? Or did Buffalo Bob ride his donkey and follow those wolves down those routes.. This is insufficient data that would be laughed out of a court room.. “The wolves did it on their own”, the “wolves were here all along”, “the wolves rode down in pickup trucks and were dropped off”.. All opinions backed by nothing. Nice picture of the opinion though.. It does leave out the late 70s early 80s Wyoming sightings south of YNP.. You’d think the Grizzlies would do it too… So since there are recorded wolf sightings going back to the late 1970s why did the wolves fail to establish a population? Or if some wolves survived the removal process of the early 20th century, again, why did the wolves fail to establish a population. Yet in 1995 the program to reintroduce wolves did rather quickly established a population.. So I’m going with wolves migrated down here from Canada in cages at various times over the years and were released.. Those attempts for whatever reason failed.. Myself and people in the family observed wolves near Bear Valley and Goat Mountain just west of the Sawtooth Wilderness in the 1970s{We did not think about shooting them}. There is no solid evidence supporting how those wolves came to be in these regions of Idaho prior to 1995..There are only opinions.
