Research the rich Geological History of how the Appalachian Mountains were built and eroded away over the past ≈500 million years. Provide detail into how the Gap itself formed (specifically from what geological time period & process) and how the layers in the photo below depict the differences that are seen now-a-days and how they relate to the paleo-environment. The paleo-environment discussion should include the absence of types of ocean forming strata, as well as other strata that was uplifted during this time.
