Dakota Hogback east of El Dorado Canyon, near Boulder, CO. This sandstone ridge (hogback) was deposited ~ 100 million years ago along the eastern edge of the north-trending Cretaceous Seaway, which divided North America. Dinosaur tracks are found in the Dakota Formation. The ridge was raised during the Laramide Orogeny (mountain building event) 63 million years ago. In this photo, the Dakota ridge is separated from the rocks to the left/west by a fault which extends up Shadow Canyon to Bear Peak in the background. Rocks in the distance are faulted blocks of the Fountain Formation--the right/east ridge forms the Flatirons; the left/west ridge forms the crags within El Dorado State Park.
