Several transcontinental time lines are drawn at selected moments in the text-glimpses of paleogeography, sweeping pictures of the United States as it appeared at some far gone date in the former world. There is a late Triassic journey in Basin and Range (28-31), and time lines from the Mississippian and Pennsylvanian periods (92-95) are a part of the deep-time set piece. As a way of introducing the idea of time lines, Basin and Range first presents a rapid transcontinental traverse through the physiographic provinces of the here-and-now (25-28). In In Suspect Terrain, there’s a Cambrian and Ordovician pair (189-91), and a pair from the Silurian ( 199-201). The earliest plants to appear on land came after the first and before the second of those Silurian time lines. In Rising from the Plains, an Eocene time line (409-10) starts from both east and west and meets in a huge lake in what is now Wyoming. After Basin and Range deals with plate theory in presentational fashion, Anita Harris, of In Suspect Terrain, in several ways attacks it. In Suspect Terrain was constructed in four panels: i. the biography of Anita Harris; 2. the Delaware Water Gap as a fragment of the Appalachians (understand a zakelijke energie fragment and you’ll have gone a long way toward understanding the whole); 3. the Appalachians and plate tectonics; + the theory of continental glaciation (used here to contrast its lack of acceptance in the nineteenth century with the experience of plate theory in the twentieth). The four panels are not presented as such, but they are distinct for anyone who cares to notice: i. pages 147-82; 2. pages 182-209; 3. pages 209-44; +pages
254-75. Note the ga.p between 244 and 254. It contains short set pieces on coal and petroleum. The narrative, at that point, is in western Pennsylvania, and western Pennsylvania is a prime place to go into both of those subjects. The Delaware Water Gap panel is a freestanding experiment, a composition within a composition. Human history there (a few thousand years) is set in duet with the geologic history, to help make some sort of point. The ambition of the text relates closely to zakelijke energie vergelijken the George Inness painting on page 146. Tell me what made that scene and you will tell me what made the eastern United States. Look over the shoulder of the painter and see how it was done.
