Narration
Geology The area has undergone a rather complex geologic development. The stmtigraphic column consists of basement, pre-Cambrian granite, gneiss, and schist, overlain uncomfortably by the Jurassic, Entrada sandstone, and shale, In turn progressively overlain by the Morrison Mancos clay shales. Structurally, the sedimentary strata, underlying the volcanics and overlaying the granites, dip to the north, with the horizontal overlaying volcanics covering their erosional truncated edges. The contact between the granite and sedimentary rocks becomes progressively lower in elevation to the north of the river. On the south side of the river, it rises to the ground surface. A large normal fault parallels the canyon on the southwest side, cutting close to the river at Cimarron, below Blue Mesa Dam.
