Geocache Description:

This Earthcache is located in the Ocoee River Gorge of Southeast Tennessee. Just off of Hwy. 64, there is a pull off with enough room for 2 or 3 cars to park, please be careful of the traffic and stay out of the road.

The Earth is about 4.5 billion (4,500,000,000) years old. Over long periods of time, ancient continents have moved great distances, oceans have formed and later disappeared, and mountains have risen and worn away. Geologists read the history of the Earth, in part, by studying the rocks at the surface. Present-day locations of different types of rocks, and the minerals, textures, and structures (faults and folds) within rock units, are largely the result of plate tectonics - the formation, movement, and collision of plates (continent-size, rigid slabs of solid rock).
570 to 240 million years ago (during the Paleozoic Era)A chain of volcanic islands moving westward on a crustal plate collided with the ancestral North American plate, causing huge sheets of rock to be thrust westward along faults or breaks in the rock layers. A second collision occurred later when the Iapetus Ocean closed and the ancestral African plate (called Gondwanaland) collided with the ancestral North American plate to create a supercontinent known as Pangaea. Rocks buckled into folds and large blocks of rock slid over each other along the Great Smoky fault. Heat and pressure increased due to these collisions and transformed sedimentary rocks into metamorphic rocks. For example, shale became slate. These events built the present-day Appalachian Mountains.
To log your find, go to the listed coords and get a picture of you with your GPS in hand with the Fold in the background and post the picture with your log. Then email me the estimated height of the fold that is showing in the road cut along with a description in your own words on how the fold was formed. Do not post your answers in your log.

Any logs without the required picture and emailed information will be promptly deleted.
