This one is in "Superman Unchained," No. 2.
Batman mentions to Superman that he lost track of a target over the Utah desert.
So, Superman heads there to check it out. He runs into General Lane, who has black hole laser weapons ready to take on the Man of Steel.
-In issue No. 3 of "Unchained," the first three words in the comic are: "The Utah desert."
Later it is "Eight hundred feet below the Salt Flats."
--About two months ago, the Smallville Season Eleven Special, No. 1, comic, dated July 2013, mentioned Superman being in Utah.
On page 16, the Watchtower reports to Batman that Superman is in Utah, "on mission."
Batman responds, "Of course he is."
--I also noticed what looked like a Utah kind of arch rock formation in the new "Man of Steel" movie.
So, the Beehive State seems to be on Superman's map lately.
