Dinosaur Tracks

A meat-eating dinosaur left these tracks in silt some 170 million years ago, when this baked plateau was a marshy plain threaded with shallow streams. The three-toed prints belong to a Dilophosaurus, a hunter perhaps twenty feet long, and were lifted from a nearby side canyon in a slab of Kayenta sandstone. That red-orange rock runs throughout Glen Canyon, a drowned and buried world turned to stone, then cut open again by the river and weathered back into daylight.
