Silver Reef Trail and Red Cliffs Dinosaur Tracksite

Sweeping views of surrounding redrock cliffs accompany interpretive panels that explain the site’s scientific significance and offer guidelines for protecting these fragile fossils. The trail and trackway lie where the Kayenta Formation transitions into Navajo Sandstone—river-deposited siltstones and mudstones layered with wind-blown sandstone. Tracks were preserved when dinosaurs walked on soft sediments along stream or lake margins during intermittent wetter climates approximately 190 million years ago, during the Jurassic Period. Identified ichnotaxa include Grallator, Kayentapus, and Eubrontes—likely made by bipedal carnivorous theropods such as Megapnosaurus and Dilophosaurus. Additional dinosaur tracks may be seen along the Red Reef East Trail. Silver Reef was mined for silver hosted in sandstone – a unique occurrence that is historically notable for being the only known silver ore deposit in sandstone. Hours and Seasons Open year‑round. Spring and fall provide the most comfortable temperatures for short hikes and viewing the tracks, while summer heat can be extreme.
