UFO crash site
In the New Mexico territory, look near Roswell to find a small flying saucer that has crashed and little green aliens with an SOS sign in the sand. When you go over that particular hex, at the bottom where it tells you what kind of land form you are on, instead of reading "Hill" it displays "(???)Hill".
