The posted coordinates will take you to a "Cutbank" along Beargrass Creek in Brown Park in Louisville. This Earth Cache IS handicap accessible, with ample parking nearby, as well as playgrounds and restrooms.
A cut bank, like to one you will see here, is an erosional feature of streams. Beargrass Creek runs and meanders for miles, and over it's lifetime has formed several cut banks through out it's total length. Cut banks are found in abundance along mature or meandering streams like Beargrass Creek and are located on the outside of a stream bend, known as a meander. They are shaped much like a small cliff, and are formed by the erosion of soil as the stream collides with the river bank. As opposed to a point bar which is an area of deposition, a cut bank is an area of erosion. Typically, cut banks are vertical and often expose the roots of nearby plant life, which actually help to prevent excessive erosion. During periods of high rainfall and higher-than average water levels, trees and poorly placed buildings can fall into the stream due to mass wasting events. Not only can cut banks be steep and unstable, but like you see here, they can also be the area of a stream where the water is flowing the fastest and the deepest. This is known as an area of high-energy,where material eroded here is deposited downstream.
In the photo above, you will notice the exposed roots of the large tree, which are a result of bank erosion. This is quite common along Beargrass Creek, and actually aides as a buffer against over eroding of the banks along it. The flow of water here, like the old rule of water "takes the path of least resistance", and tends to erode soil and forgives major erosion form the creek bed, or bedrock which is almost 100% limestone in the case along Beargrass Creek.
To log this cache, please email me the answers to the following:
1. Do you see evidence that the trees along the bank here are helping to prevent over erosion?
2. Do you see any evidence of mass wasting?
3. Do you see evidence of bank instability on either side of the creek?
4. (optional) Take a photo of yourself with Beargrass Creek in the background.
