Sternberg Museum of Natural History
Kansas
A 14-foot fossil fish with another fossil fish inside its stomach -- the famous 'Fish-within-a-Fish,' a Xiphactinus that swallowed a Gillicus whole 89 million years ago when this stretch of I-70 was seafloor. Add a giant sculpted mosasaur bursting through the museum's roof, visible from the highway, and you've got the rare Kansas stop kids beg to pull off for.
Why Roamward picked it
Anchors the far-western stretch of I-70 near Hays, where Roamward's current KS content thins out fastest. One of the finest Cretaceous marine fossil collections in the US, paid admission, on the Fort Hays State campus with easy highway access and a literal roof-dinosaur that's a built-in photo-op landmark -- strong family fit and a genuine 'worth the exit' claim for the loneliest part of the drive.
