Dinosaur National Monument (sh)




National preserve, northwestern Colorado and northeastern Utah, U.S. It was set aside in 1915 to preserve rich fossil beds that include dinosaur remains.

It was enlarged in 1938 and again in 1978 to its present 330 sq mi (855 sq km). It protects the canyons of the Green and Yampa rivers, which contain highly coloured geologic formations.
