The Cliffs at Gay Head

The Cliffs at Gay Head reveal a fascinating geological history, featuring ancient clay layers and glacial deposits that stand high above sea level today. These striking formations offer insights into events from the Cretaceous period, with some layers dating back 100 million years. Erosion has significantly shaped these cliffs, exposing rich fossil layers that tell stories of the past. Noteworthy sites like Devil’s Bridge and Moshup deepen our understanding of the region's geological processes and history, while the vibrant colors of the cliffs and water add to their allure.

Presentation Transcript

  1. The Cliffs at Gay Head

  2. The layers of clay are very very old,with a thin layer of glacial deposits on top.So why are they so high above sea level today?How is the Ice Age responsible for their visibility to us?

  3. Some layers are 100 million year old deposits, from the Cretaceous.

  4. Clay deposits are extremely soft, so the erosion is significant. Notice the color of the water.

  5. Certain layers are rich with fossils. Based on the fossils, what can you say about how these layers formed millions of years ago?

  6. A large fossil bone.But from what?

  7. The City of Columbus(A cruise ship in it’s time.)

  8. January 18, 1884

  9. Actual photograph from the next day.

  10. Devil’s Bridge(Glacial moraine and enormous erratics, just under the surface.)

  11. MoshupThe real reason for Devil’s Bridge. And Nomans Land. And the red color to the cliffs. And…
