Subsequent to this "flood," the mountain block called the Tetons was uplifted and sculpted by glaciers. Geologists universally regard the Flathead Sandstone as the basal layer of a "marine transgression" that flooded most of the continent beneath seawater. The Flathead Sandstone is the basal part of an entire succession of marine fossil-bearing strata that tilt westward away from the axis of the Teton Range but which are mostly out of view from the floor of Jackson Hole. The cap is in fact a remnant (the Flathead Sandstone) of a vast sheet of sandstone that once covered the continent like a layer of plastic wrap across a football field. Third and finally, there is what appears to be a tiny wisp of a light-colored cap atop Mount Moran, as if it needed to keep its head warm. Could these dikes such as exist atop Mount Moran mark an episode of worldwide tectonic unrest immediately prior to the start of the Flood? The evidence certainly fits with this. Scripture indicates the Flood began when "all the fountains of the great deep |were| broken up |literally ‘faulted'|" in a single day ( Genesis 7:11).
It was emplaced sometime before the erosion surface known as "the Great Unconformity" was generated, yet after formation of the crystalline basement rocks. Diabase dikes are not uncommon in the rock record, but they are an especially common feature of the "late Precambrian" worldwide and may mark a unique episode in earth history when vertical cracks were opened and infilled with mafic (iron/magnesium-rich, quartz-poor) magma. In this case, the dike is about 150 feet in width, and diabase in composition. Second, there is the peculiar black dike that from a distance looks like a vertical line made by a giant, broad, felt-tipped pen. Is it conceivable that the patchwork basement of metamorphic and igneous rocks presents the appearance of a long history of melt, intrusion, and recrystallization, yet the entire body was created instantly? Is it possible these represent the collective work of Day One of the Creation Week? One thing is certain: it is easy to identify rocks like these as forming the core of most of the earth's continents. However, these relationships are not nearly as clear as the margins of true intrusive bodies such as the Sierra Nevada Batholith, where adjacent fossil-bearing sedimentary rocks were obviously cooked by the heat of the enormous magma body. Although granitic in overall composition, most of the basement complex consists of metamorphic and igneous rocks that appear to be in crosscutting relationship with one another and which seem to indicate a long history of complex intrusive events. If you drill deep enough in most places on the continent you will find these rocks. How does this beautiful mountain testify of Creation and the Flood?įirst, the core of Mount Moran is comprised of crystalline basement rocks, the same types that make up most of the core of North America. Its face is made of the same solid granitic stock as comprises the core of the other mountains of the Teton Range, but it differs in other respects. Mount Moran, the nonconformist of Wyoming's Teton Range, is distinguished by having a blunt top, a prominent black vertical stripe on its upper part, and a tiny visible cap of marine sandstone on the summit.
