Do a search in the "elk" forum for colorado wolves. LOTS of stories from old-time CO families and hunters. They've been in certain areas of NW Colorado for years and kept quiet by local families for generations. I'm the fifth generation of my old CO ranching family to have seen them both dead and alive...don't know if some of them were illegally reintroduced or were in fact truly wild, but they've been around for years...coming down through the Zirkels, through the Silver Creek wilderness and pushing South for years is our theory. In our area they would show up around late August and hang through until the snows of October pushed them back to wherever it was that they'd come from. It's not until the past 8 years that we have seen more of them and seen them earlier in the summer months....a certain DOW officer has pictures of the same collared wolf hit and killed on I-70 a few years back taken two days before with two other big "dogs" on a certain ranch in NW Colorado...
