as a major sediment source for the Tejas megasequence. And yet we see the same pattern of very limited extent and small volumes of Sauk through Kaskaskia, and tremendous amounts of Zuni and Tejas, across all continents. Why does Africa show the same location of deposition for the first three megasequences if this is all the result of random late Flood/post-Flood uplift and erosion? Erosion should have significantly reduced the extent of earlier megasequences, leaving many small remnants of the Sauk, Tippecanoe and Kaskaskia scattered everywhere across the continents in randomly distributed patterns. We do not see a random pattern. In fact, and even more compelling, is the observation that the early megasequences are confined to nearly the same identical locations across each of the five continents, and stack uniformly one on top of the other. This is the general rule for all five continents. Random erosion would not leave this consistent of a megasequence pattern across five continents. Our study also found that all megasequences thin toward the crystalline shield areas on all continents (Fig. 16). In other words, the stratigraphic units do not show evidence of massive erosion and truncation. Instead, they all thin in the direction of the now exposed Figure 16. Stratigraphic cross-sections across North America showing the megasequences thinning toward the Canadian Shield (Clarey 2020). shields, implying they were originally deposited thinly in these areas right from the start and are not a simple consequence of erosion. Figure 16 shows four stratigraphic profiles across the northern USA. All show dramatic thinning of the megasequences from south to north toward the Canadian Shield, in support of this interpretation. In addition, these four profiles (Fig. 16) show the improbability that erosion by the receding water (or post-Flood) phase of the Flood could serve as an explanation for the limited amounts of Sauk, Tippecanoe and Kaskaskia we observe. Figure 16 shows that the rocks of the Absaroka and Zuni megasequences cover and protect the earlier megasequences, preventing their late Flood or post-Flood erosion. Therefore, the simple argument that late massive erosion can be used to explain the megasequence patterns we observe can be put to rest. B. Starting Configuration: Pangaea Before we present our progressive Flood model, we have to establish the most likely pre-Flood continental configuration. There are several competing ideas, but most Flood geologists accept either a Pangaealike configuration (Baumgardner 2018; Clarey and Werner 2018b) or CLAREY AND WERNER Progressive Flood model 2023 ICC 425
