User blog:Buzzy 85/No Mammoths??

I've been playing Skyrim for the last couple of days and have found four or five different sets of giants(that are all within areas that have the mammoth tusk on the map). My problem is that there has yet to be a single mammoth in any of the camps.

I thought at first that maybe some of the camps didn't have mammoths in them...but now I'm not sure what to think.

Is this some kind of glitch or what is going on?

Any input is appriatiated. Thanks :)
