| Gulpha Gorge Creek drains past the campgraound at Hot Springs National Park, Arkansas. The bedrock in the park is famous Arkansas novaculite, a very dense, white chert formed from deep ocean biosilicieous sediments of Ordovician age. These ancient marine sediments endured a rich and long geologic history, including being crushed between two continents during the late Paleozoic Era. At that time, mountains formed along the southern margin of North America when it collided with South America and other continents and became the supercontinent of Pangaea. |
