I believe the answer is:

utah

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for utah that I've seen before include "Mormon US state" , "The American Mormon state" , "Bryce Canyon US state" , "Mormons are found here in a hut" , "US state settled by the Mormons" .)

I've seen this clue in The Independent.
