The Cañon City Embayment (CCE), which is situated in the southernmost portion of the Denver Basin in Colorado has been described as an area with complex geology. Newly observed tectonostratigraphic relationships in the area have been documented through detailed lithologic and structural mapping. Two generations of thrust faults and two generations of unconformities are present and are interpreted to be linked to the Ancestral and Laramide orogenies, respectively. Structural measurements and analysis of bedding planes, faults and fault zones, joints, slickensides, deformation bands, and unconformities show that these structures are consistent with the NW-SE orientation like those of the Ancestral and Laramide uplifts. Radiometric age dating in future studies would provide exact ages of the unconformities and thrust faults.
