Geology Underfoot Along Colorado's Front RangeThe transition from the relatively flat Great Plains to the craggy peaks of Colorado's Front Range is one of North America's most abrupt topographical contrasts. The epic, 1,800-million-year geologic story behind this amazing landscape is even more awe inspiring. The 21 chapters, or vignettes, in Geology Underfoot along Colorado's Front Range narrate this tale, from the Front Range's humble beginnings as a flat, nondescript seafloor through several ghostly incarnations as towering mountain ranges. At easily accessible stops along the Front Range's highways and byways you'll meet the apatosaur and other dinosaurs who roamed the floodplains and beaches that once covered the Front Range; look for diamonds in rare, out-of-the-way volcanic pipes; learn how America's mountain, Pikes Peak, developed from molten magma miles below the surface only to become an important visual landmark; and walk the Gangplank, a singularly important plateau for both nineteenth-century westward expansion and our understanding of the Front Range's most recent exhumation.
