From the Telluride Daily Planet in Colorado:
For millions of years, gray wolves roamed this continent.
Thousands of them once lived in Colorado, but by 1935, wolves were effectively extinct here — scientists call it “extirpated” — from gunshots, poisoning and trapping. No one knows for sure where the last wolf died in this state. One writer believes it was in the South San Juans in 1938 (the South San Juans are where Colorado’s last grizzly bear died in 1979). Another speculates the year was 1945, and the wolf’s place of death was Conejos County, on the border of New Mexico.
