Did you know that the flank of the Front Range between Lyons and Livermore is a microcosm of the Wyoming Province of the Rocky Mountain Foreland? Here Laramide structures are exposed in a manner that reveals the relationship between folding of the sedimentary package and block faulting of the Precambrian basement. Displayed here are monoclines, domes, basins, and asymmetrical anticlines and synclines. In this small area, one can observe virtually all styles of Laramide deformation found throughout Wyoming and other parts of the structural province. In the subsurface of the Denver basin eastward to Greeley, the producing structural traps reflect the fold geometries found along the mountain front.
