300 million years to today8 places48 kmSaved at every border

The ground under Colorado Springs has been a mountain range, a desert, a swamp full of dinosaurs and the floor of a sea. This ride crosses all of it in order. Stegosaurus grazes by the river. Theio wanders the ferns. Mosasaurs swim under the causeway where downtown will be. Then the mountains rise and stand the layers on end, and you finish at Garden of the Gods.

QUESTIONS

Was Colorado Springs under the ocean?

Yes. Around 100 to 70 million years ago the Western Interior Seaway covered the middle of North America, including where Colorado Springs is now. Most of the city sits on its old sea floor, the Pierre Shale. Mosasaurs and ammonites swam there.

How did Garden of the Gods form?

The red rocks started as gravel washing off the Ancestral Rockies and as wind-blown dunes, about 300 to 280 million years ago. When the Rockies rose again 70 to 60 million years ago, the layers were tilted until they stood on end as the fins you see today.

What is Theio?

Theiophytalia, the Garden of the Gods dinosaur: a plant eater found in the park in 1878, misfiled at Yale for over a century and named as a new species in 2006. Its skull is the only one known.

Are there Stegosaurus in it?

Yes, on the Morrison floodplain leg. Stegosaurus is Colorado's state fossil. Point at any animal or plant and a label names it.

Is it good for kids?

Yes. There is no racing and nothing to shoot. Kids can ride with the arrow keys, point at animals to learn what they are, and press B for binoculars.

How long is it?

48 km in eight legs of 6 km, with your spot saved at every border.
