This is an easy to access Earthcache. Access is available by both a sidewalk, on the 6600 block of North College Avenue Bridge, or via the coordinates on the Monon Trail. The latter is a very smooth public access paved trail with parking just south of the coordinates. This is ideal for those who use wheelchairs and strollers.
This location is just east of the confluence of the White River and Williams Creek.
Flowing water plays a major role in erosion by carrying away soils and other materials on the land surface. In general, there is a potential for water erosion where the land slope is at least 2 percent. The four types of water erosion of soil are sheet, rill, gully, and tunnel.
Confluence - Confluence, in geography, describes the meeting of two or more bodies of water. It usually refers to the point where a tributary joins a more major river. A notable confluence is the merging of the Monongahela and Allegheny Rivers. This merging point is the beginning of the Ohio River, thus forming a confluence in Pittsburgh. Then the Ohio meets the Mississippi for another notable confluence. The confluence of the White River and Williams Creek is very minor, but by definition is the same as the confluences described above.
River -A river is a natural watercourse, usually freshwater, flowing towards an ocean, a lake, a sea, or another river. In a few cases, a river simply flows into the ground or dries up completely before reaching another body of water. Small rivers may also be called by several other names, including stream, creek, brook, rivulet or tributary.
Sediment-Sediment is naturally-occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of fluids such as wind, water, or ice, and/or by the force of gravity acting on the particle itself.
At confluences one often sees changes in the common current due to the influx of the secondary water flow. In addition, one can often see signs of sedimentary flow and deposition. The deposition can result in the formation of islands, sandbars or spits. This deposition can also build up the low lying floodplain. These depositions will occur downstream from the confluence and in the lower flow sections of waterways due to the current.
Ancient sedimentation can form rock such as limestone, which has been used for construction. More recent sedimentation is often loose and transitional, a poor material for use as a building material, not to mention unstable for a building site.
To Log this cache:
A)-Email any signs of erosion and deposition
B)-Describe the formation formed by sedimentation, paying specific attention to the texture and makeup of the sedimentation and the length and width
C) Is the sedimentary material a good site for construction or for use as a construction material
Optional
D) post a picture if you like
