Definitely not little, it's actually the 8th-largest state of the USA, and larger than many countries (it's a little smaller than Italy). It's a weird one, because the West and East side are totally different: mountainous on the West side, flat in the East. The population lives mostly on the border between the two side, is very highly educated, mostly liberal for the USA, and is absolutely obsessed with the outdoors.
The mountain side boasts some of the most gorgeous landscapes on Earth. The orogeny that led to their creation was rapid, unusual (in that it was mid-craton and not on the edge), and recent, so that they are jagged and rough and wild. If you'd like to get an idea, just look up "San Juan mountains" in your image search engine of choice.
