ABOUT THIS LOCATION
This Earthcache will bring you to Ridge Run Park which is part of the Washington County Park system located in West Bend. The Park hours are posted at the entrance, 6 AM until 9 PM. This earthcache is located near the Orrin J. Peters reserved picnic areas which can be reached off Scenic Drive and Wheat Ridge Lane (N 43 24.772 W 88 13.563). There are two different entrances to this park HOWEVER the road in the park is closed to vehicle traffic between the two sides.
There were four major stages of Ice Age Glaciations that left their mark on the topography and soils of Wisconsin. The last stage, called the Wisconsin stage, ended approximately 10,000 years ago. Ridge Run Park has many Ice Age features for you to discover. I selected this location because it is located just off the Wisconsin Ice Age Trail. The outwash plains left stratified deposits consisting of gravel, sand, silt and clay, laid down by water from the melting ice fronts.
The water in an artesian well flows from an aquifer, which is a layer of very porous rock or sediment, usually sandstone, capable of holding and transmitting large quantities of water.
The geologic conditions necessary for an artesian well are an inclined aquifer sandwiched between impervious rock layers above and below which trap water in it.
Water enters the exposed edge of the aquifer at a high elevation and percolates downward through interconnected pore spaces. The water held in these spaces is under pressure because of the weight of water in the portion of the aquifer above it.
If a well is drilled (or dug) from a land surface through the overlying impervious layer into the aquifer, this pressure will cause the water to rise in the well. In areas where the slope of the aquifer is great enough, pressure will drive the water above ground level in a spectacular, permanent fountain.
Artesian springs can occur in similar fashion where faults or cracks in the overlying impervious layer allow water to flow upward. Water from an artesian well or spring is usually cold and free of organic contaminants, making it desirable for drinking.
Pascal's law predicts the theoretical hydrostatic pressure P:
where p (rho) is the density of the fluid, g the acceleration due to gravity, and z is the elevation. In practical terms the pressure is expressed as metres water column (zr - zw).
Enjoy your visit!
To log this earthcache, you must complete TWO tasks.
1) YOU SELECT THE TASK
a. Bring a thermometer and email me the temperature of the water on the day of your visit OR b. Bring a container of known volume and email me how many gallons per minute are flowing from this artesian well. OR c. Bring your ph testing strips and email me what the ph reading of the water on the day of your visit. IT IS NOT ADVISED THAT YOU DRINK THE WATER FROM THIS ARTESIAN, IT IS NOT TESTED ON A REGULAR BASIS.
2) BRING YOUR CAMERA. We would like a photo of your team with your GPSr showing the Artesian Well. However, if you are solo caching, a photo of your GPSr with enough of the location in the background that can be identified, will also be accepted. Please upload your photo(s) with your "found it" log.
Please be advised, failure to complete the TWO tasks listed above (emailing the answer and posting your photo will result in log deletion without notice.
You do NOT have to wait for confirmation from me before logging your find. Please do not make any reference to these answers in your log.
is the cache designation to highlight a series of Earthcaches "ColdCaches" along the Ice Age National Scenic Trail.
The Ice Age Trail is one of seven nationally designated trails by the National Park Service and of these seven, the only trail that is unique to just our state.
This is a project of the Ice Age Park & Trail Foundation to bring more visitors to the trail. More information will be available at: Ice Age Park & Trail Foundation
