Dinosaur National Monument

The broader setting for Dinosaur National Monument is at the confluence of the Green and Yampa Rivers. Jeremy Sell (https://thelifeofyourtime.wordpress.com/2013/08/20/dinosaur-national-monument/)

Dinosaur National Monument is spread over 210,000 acres along the Colorado and Utah border, and encompasses spectacular scenery, in addition to offering a unique exhibit hall that is carved out of an ancient river bed. The site was designated as a National Monument over 100 years ago, in 1915, and displays an estimated 1,500 dinosaur fossils visible in a cliff face at the famous Carnegie Quarry, most of which appear to have been washed into an ancient river bed.

Dinosaur National Monument straddles the state lines of Colorado and Utah. Most of the Monument's terrain is located in Moffatt County, Colorado, but the main museum structure - Quarry Exhibit Hall - is located just north of Jensen, Utah.
