Triceratops Trail

Triceratops Trail is a short out-and-back trail near the Colorado School of Mines in Golden. Fossil tracks and fossil plant impressions paint a picture of what Colorado looked like 66 million years ago – just prior to the mass extinction that marked the end of the non-avian dinosaurs.

Rocks that were originally horizontal have been thrust up to a vertical orientation when the Rocky Mountains formed. Clay layers were mined out so that now you walk down into these ‘canyons' to see the trace fossils. Tracks from tyrannosaurus, triceratops and hadrosaurs are present, along with traces of palm fronds and deciduous leaves.

You can pay-and-park in the Colorado School of Mines parking lot A at 1400 Jones Road and walk ¼ mile southeast along the bike path where you will see the Triceratops Trail kiosk and trailhead. This short gravel trail has multiple informational signs to guide the way. Further information is available at the Dinosaur Ridge Visitor Center (contact information below).
