The state of Nebraska was divided up into 24 Natural Resource Districts (NRDs) in 1972 by an act of the Nebraska Legislature. In 1989 the Papio NRD and the Middle Missouri Tributaries NRD were combined into the Papio-Missouri River NRD and making the number 23. The 23 NRDs are shown below.

The Papio-Missouri River NRD is on the Eastern side of Nebraska (brown on the above map). It contains about 4 ½ counties; Dakota, most of Thurston, half of Burt, Washington, Douglas, and Sarpy as shown by the below map. The main waterway is the West Papillion (usually shortened to Papio) Creek. The Papio Creek is in all over 15 miles long and its main uses are flood control and surface water deposition. Many of the storm drains in Omaha, the largest city in the NRD, drain into the West Papio creek which carries that water to the Missouri River.

To get credit for finding this cache you must:
- Go to the listed coordinates.
- Go to the east side of the trail.
- You can obviously see the erosion caused by the creek. Now, answer these questions:
- How has man tried (and failed) to stop the erosion?
- How has nature now begun to control the erosion?
- When you have your answers, email them to me.
- After you send the email, make your log below.
