These are some of the views of Makoshika, which is just outside Glendive, Mt where I grew up.
We hiked and played in the area, never realizing it was rich with dinosaur bones and impressions in the sandstone.
My nephew Dave is Dinosaur Dave there and shows this T-Rex rib in the sandstone.
This is a Triceratops jawbone which is at the Museum of the Rockies. Dave found it several years ago and submitted it to the museum.
