70 million years ago the Laramide orogeny uplifted the Sangre de Cristo Mountains, steeply tilting the earlier sediments down to the east.
Although the present topography of the range and adjoining basins is controlled by extension during rifting in the last 10 million years, faults within the range also record deformation during the Laramide orogeny, between 85 and 45 million years ago.
