A few online resources related to life in the Mountain West:
High Country News:
http://www.hcn.org/. Regional Western issues, from a generally liberal perspective. Kind of a regional alternative newspaper.
Some rural public radio stations, which from what I've heard, have similar mixes of programming -- lots of alternative country and bluegrass, especially on the music programming. They've got a really different feel from most urban public radio stations that I've listened to. All of them stream broadcasts online, so if you want to listen to a bit of the Mountain West while working or whatever, you can check them out:
Four Corners Public Radio
www.ksut.org: Southwest Colorado and northern New Mexico, with a little bit of broadcast area into SW Utah and NW Arizona.
Mountain Grown Public Radio
http://www.kvnf.org/: The Western Slope of Colorado, heard from Ridgeway to Grand Junction.
Wyoming Public Radio
http://uwadmnweb.uwyo.edu/wpr/: The only public radio station in Wyoming. I've caught it around the Green River area in SW Wyoming, but I suspect it has transmitters all over.
A lot of the media that dominates the West isn't home-grown. On the radio, there are the same Clear Channel country stations and right-wing talk radio that you can hear anywhere in the country. For newspapers, there's USA Today, or the nearest city newspapers (Denver, Salt Lake City, Albuquerque), or there are small-town papers that get most of their stories from Reuters or AP. The locally produced stuff, weirdly enough, seems to be dominated by liberal transplants, rather than by people who have lived in the area for generations. But the transplants love their home, and talk about things from a regional perspective, even if they've lived in other parts of the country at other times in their lives.
