Tilted rock layers: The sedimentary layers in this large roadcut near Denver, Colorado, USA can be clearly recognized by the variation in colour. These layers can be recognised as having been deformed because they have been tilted so they are dipping to the east (the left side of photo). This deformation was related to the uplift of the Rocky Mountains.

The road cut in on I-70 near Golden, CO. There are signs explaining the geology of the Cretaceous section. This was an initiative of the Colorado School of Mines spearheaded by Dr. Robert Weimer in early 80's.
