K-T boundary

From NASA’s Earth Observatory: Raven Ridge, Colorado.


This ridge, south of Dinosaur, Colorado, apparently has an exposure of the K-T (Cretaceous-Tertiary) boundary, which marks whatever event ended the age of dinosaurs (asteroid? volcanism? the real reason dinosaurs went extinct?). This gives me two places within a day’s drive to visit the K-T boundary, the other being down by Raton, NM. It looks like a good place for a road trip, with the addition of nearby Dinosaur National Monument.

Grace and Peace
