This is a good descriptive book with black and white drawings and one section of around 50 color pics. It should come in handy in the Colorado Rockies. It's always a good idea to get a couple books like these on the same topic by different authors, or search the internet, to cross-reference and double and triple check to make sure that you've properly identified each species.
