The exposed rock that you see along the Mississippi River is mainly sedimentary. The events that formed the area surrounding the Mississippi river tell a story about what has been there before. The igneous rocks present at the surface and under the surface near the site of the Mississippi River were formed by areas deep below the surface of the earth which have liquid magma in them; the liquid magma comes to the surface when a volcanic eruption occurs. The presence of Benotite on level C shows that there was some volcanic presence in this area. Otherwise, this type of rock would not be existent. There is also a possibility that a glacier brought this rock here in its travels. The softness of the volcanic ash shows us that it might not have been here for a long time, or it might be the outcome of a small eruption.
             Metaphoric rocks are also present in this area, and we found them on every level we encountered. These rocks were formed by the pressure being so great that they were transformed into stone. Especially near areas where there is a vast amount of water, you can find sedimentary rocks. Those rocks are made of soil, sand, dust, and organic material deposited later and pressed together to form stones. The currents of oceans, or rivers, in this case, move the rocks and reorganize them.
             The softness of the ground was a key indication that this used to be the sight of an ocean. The shores of oceans are generally softened over time by the current and waves crashing into them. We also found various fossils on our outing to the Mississippi, which led us to consider this an ocean area because of the origin of these organisms. We found both Bryozoans and Brachiopods. Bryozoans, or "moss animals," are aquatic organisms living for the most part in colonies of interconnected individuals. Brachiopods were also found, which is entirely miraculous. Branchiopods are marine animals found in only the coldest parts of waters, which happen to b...
