I just answered this one last week.

It's 9.5 degrees east declination in Denver. By the time you get to the Utah border it's up to 11 degrees.

The first guy's map is almost 20 years old. Here's an NOAA site with the latest (updated daily) magnetic declination info.

If you are near the Crazy Mountains in Montana (which everybody and their dog seems to be asking about lately), it's 12.8 degrees.

You can get it from a map:
