A Hike to the KT (K-Pg) Boundary

The K–T Boundary (now more accurately called the Cretaceous–Paleogene or K–Pg Boundary) marks a major episode in Earth's history that happened approximately 66 million years ago. This unique spot in the park precisely marks one of the most significant extinction events on our planet. A point in time when about 75% of all species on earth became extinct, including nearly all dinosaurs. Here in Trinidad Lake State Park, a readily visible, thin layer of sediment marks the K-Pg boundary. Like a snapshot, it records a sudden global catastrophe when one period of Earth history ended and another began. Join us and see this fascinating spot for yourself.

All events are free to the public. Vehicles are required to have a Colorado State Park Pass.
