A Mississippi River Experience

The igneous rocks that are present at the surface, and under the surface near the area 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. With the presence of Benotite on level C it shows that there was obvious some type of 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.

With all the different fossils, rocks, and minerals its obvious that something brought them there, and this is not where all of these things originated. The traveling glaciers, as mentioned before, may have picked up these different minerals and rock and transported them to the area. These rocks were formed by the pressure being so great that they are transformed into that type of rock. We found both Bryozoans and Brachiopods.

Especially near areas where there is a vast amount of water you can find sedimentary rocks. The shores of oceans are generally softened over time by the currant and waves crashing into them. The currants of oceans, or rivers, in this case move the rocks and reorganize them. Bryozoans or "moss animals," are aquatic organisms, living for the most part in colonies of interconnected individuals. The rocks and minerals that form the walls of the Mississippi river are very soft, and as we travel down, become softer, telling us that something was hitting these rocks hard, possibly an ocean currant or waves. are also present in this area, and we found them on every level we encountered. Those rocks are made of soil, sand, dust, and organic material are deposited layer after later and pressed together to form rocks. There were different colors, different sizes, and many differently harnesses. If there was any type of volcanic eruption it would have been very small because the amount of volcanic ash that was and has been found is minimal.

The extensive variety of rocks and minerals found near the Mississippi river area tells us that glacial occurrences may have been possible.

The softness of the ground was a key indication that this used to be the sight of an ocean.
