Geocache Description:

This EarthCache is located south of Menomonie Wisconsin. Many people have been to this area, but few actually know what exactly is happening here.
Welcome to the Weeping Wall.

This wall actually 'weeps' year round..... but why?

A spring is a point where groundwater flows out of the ground, and is thus where the aquifer surface meets the ground surface.

Water issuing from an artesian spring rises to a higher elevation than the top of the confined aquifer from which it issues. When water issues from the ground it may form into a pool or flow downhill, in surface streams. Sometimes a spring is termed a seep.

Minerals become dissolved in the water as it moves through the underground rocks. This may give the water flavor and even carbon dioxide bubbles, depending upon the nature of the geology through which it passes. This is why spring water is often bottled and sold as mineral water, although the term is often the subject of deceptive advertising. Springs that contain significant amounts of minerals are sometimes called 'mineral springs'. Springs that contain large amounts of dissolved sodium salts, mostly sodium carbonate, are called 'soda springs'.

Although not evident in the winter (mainly because of the ice that is present), there is evidence that minerals are present in this spring water as well. The wall of the ravine is stained by brilliant hues of orange and gold. This indicates that high levels of iron are dissolved in the water.

The 'weeping' wall you see now is the product of erosion caused by melting glaciers approximately 10 thousand years ago.

These erosional forced carved a distinctive channel into the limestone. The ravine formed, exposed 'veins' of spring water that continually 'weep' from the ravine wall.

Two characteristics of this water are very interesting, and you might find them very surprising.

So, to receive credit for this EarthCache, please do the following:

Previously I mentioned that two of the characteristics of the water here are very interesting, please measure the temperature and the pH of the water. (pH strips can be obtained at any pool supply store or even pet stores.)

Is the water basic or acidic?
Why is it basic/acidic?

What is the temperature of the water?

Please e-mail this information to me when logging this EarthCache.


When logging this EarthCache, please upload a picture of yourself/team with your GPS clearly visible with the Weeping Wall in the background.


Logs that do not meet these criteria, Will Be Deleted, No Exceptions!!

Please Note: The area to park to access this EarthCache is very limited, be sure to pull off of the road as much as possible.

Also, even though this EarthCache is for the entire family and may be accessed year round, this area may be VERY icy during the winter. Please use caution in this area during our colder months. At no time should you be near the wall, the necessary information to be gathered can be accessed WELL AWAY from the wall.
