ABOUT THIS LOCATION
Wisconsin is said to be one of the best places to witness the many landforms created by the Ice Age glaciers. Your quest for this Earthcache is a visit to the Kettle Moraine Southern Unit.

Nemahbin Spring is located along the Wisconsin Ice Age Trail. Although this is state land, a yearly sticker or daily admission fee IS NOT REQUIRED if you park at N 43 03.103 W 88 24.840. There is parking for several cars here to enjoy the Ice Age Trail. Please use the parking coordinates and do not park along the road way to bushwhack to the Spring due to the ecological damage you will cause. The Spring is approximately .54 walk along the Ice Age trail from the parking area.
GEOLOGICAL INFORMATION
Nemahbin Spring was formed by the movement of the Ice Age Glaciers. As the glaciers flowed over the area, it softened and lifted out blocks of rock, which were moved out of the area by the moving ice. (This process is known as plucking). The rate of glacier erosion is variable and is controlled by several factors. Some of these factors include: Velocity of glacial movement, thickness of the ice, shape and hardness of rock fragments contained in the ice at the bottom of the glacier, and permeability and water pressure at the glacier base.
As you can see, the glaciers excavated the side of the hill where the spring is located. The spring was formed because there was a natural flowing body of ground water at or below the local water table where the subsurface material was saturated with water. A spring is formed as a result of an aquifer being filled to the point where the water overflows onto the land surface.

To log this earthcache, you must complete 4 tasks.
1) BRING YOUR CAMERA (Optional). We would like a photo of your team with your GPSr at the Spring. However, if you are solo caching, a photo of your GPSr with enough of the Spring in the background that can be identified, will also be accepted. Please upload your photo(s) with your “found it: log.
2) BRING a yardstick. Measure the depth of the spring at the opposite end from the river spillway spring run off – see photo.

3) BRING a compass. Observe the direction the water is flowing to the river spillway spring run off. What direction is it flowing?
4) OBSERVE the Spring basin. What shape is it?
Email your answers to the respective tasks when posting your “found it” log.
Please be advised, failure to complete the tasks listed above may result in log deletion without notice.
You do NOT have to wait for comfirmation from me before logging your find. Please do not make any reference to these answers in your log.

![]() IATCC is the cache designation to highlight a series of EarthCaches along the Ice Age National Scenic Trail grouped into a special category called "ColdCache."
The Ice Age Trail is one of eleven (11) National Scenic Trails designated by the National Park Service. This unique trail is entirely within the state of Wisconsin and follows along the terminal moraine of the most recent glacier.
This project is supported by the Ice Age Trail Alliance. The goal is to bring more visitors to the trail and promote public awareness, appreciation, and understanding of Wisconsin’s glacial landscape.
More information on the Ice Age Trail Atlas, the ColdCache Project and Awards Program is available at: www.iceagetrail.org/hiking-awards-and-programs.

The Geocache Notification Form has been approved by Paul Sandgren, Forest Superintendent of the Southern Unit Kettle Moraine State Forest of the Wisconsin DNR. Geocaches placed on Wisconsin Department of Natural Resource managed lands require permission by means of a notification form. Please print out a paper copy of the notification form, fill in all required information, then submit it to the land manager. The DNR Notification form and land manager information can be obtained at: http://www.wi-geocaching.com/hiding
I have been trying to find historical information about this Spring without much success. If you know more about when the basin was formed, I will update this cache page.
