Mill Canyon Dinosaur Trail
The Mill Canyon Road is a west turn off of Highway 191 just north of Mile Post 141, north of Moab in southeast Utah. After 0.6 miles there is a staging area and an information kiosk. Signs point the way another 1.1 miles to the parking area for the Dinosaur Trail.
A shorter version of the Lower Monitor and Merrimac Loop bike and hiking trail can start from the same parking area. The Dino Trail is a 0.8 mile interpretive loop with many fossils visible.
The interpretive signs at the trail head mention that the deposits here are sandstones, clays and shales of the Morrison Formation from 155 to 144 million years ago. These rocks are a little younger than the Entrada Sandstone that forms most of the Arches that are famous in the area. The fossils found here include Camptosaurus, Allosaurus, Camarasaurus, and Stegosaurus.
