Torreya is all about erosion. There are many items, like waterfalls, that are rare items for florida. This item is rare for any area.
Stream capture, river capture, or stream piracy is a geomorphological phenomenon occurring when a stream or river drainage system or watershed is diverted from its own bed, and flows instead down the bed of a neighbouring stream. This can happen for several reasons, including:
- Tectonic earth movements, where the slope of the land changes, and the stream is tipped out of its former course
- Natural damming, such as by a landslide or ice sheet
- Erosion, either
- Headward erosion of one stream valley upwards into another, or
- Lateral erosion of a meander through the higher ground dividing the adjacent streams.
- Within an area of karst topography, where streams may sink, or flow underground (a sinking or losing stream) and then reappear in a nearby stream valley
The additional water flowing down the capturing stream may accelerate erosion and encourage the development of a canyon (gorge).
The Apalachicola is the largest river in Florida, with parts of the basin extending to Georgia and Alabama. It was once a small tributary to thge Chatahoochee River and was confined to Florida. Over time, it eroded a path/valley through the hills and captured the Flint River. The Chatahoochee, deprived of its major tributary, moved eastward and joined the flint river, which now makes up the current Apalachicola.
Logging requirements:
1. Look at the surrounding area and describe what features would make this area fertile for a river capture. 2. Discuss the water flow of the current Apalachicola and describe what impact that may have.
