How Geocaching Works

Please note Use of services is subject to the terms and conditions in our disclaimer.

Geocache Description:

Lodi Marsh is a wildlife area that provides a variety of recreational activities.  Dogs must be on a leash from April 15 through July 31.  Also, please refer to the DNR website for trapping and hunting seasons dates.

The Lodi Marsh formed after the last glaciation as a wetland vegetation slowly filled a shallow pond in part of the valley.  The trail crosses a low part of the marsh, a slightly higher area, then onto two higher east-west trending drumlins.

A drumlin is an elongated, whale-shaped hill that forms at the bed of a glacier.  They form when there are numerous hard and soft spots on the glacier bed.

The ice deposited material around a small obstacle on the ground.  Individual surges of the glacier added more material creating layers and then reshaped the deposits by further ice movements.  They can be composed of nearly all bedrock, nearly all sand, a mixture of sand and gravel, or all till.  Drumlins occur in groups called drumlin fields or swarms.  The steep end of a drumlin faces into the ice flow, while the back of the slope became lower as the ice passed. 

Drumlins deposited near the center line of a moving glacier, where the ice was thickest, are long and narrow.  Those deposited closer to the glacier’s margins, where the ice was thinner, have a rounder outline. 

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 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 which retreated about 10,000 years ago.  

This project is supported by the Ice Age Trail Alliance (IATA).  The goal is to bring more visitors to the trail and promote public awareness, appreciation, and understanding of Wisconsin’s glacial landscape. 

The IATA has created an awards program to encourage visits to the trail and ColdCache sites.  This awards program is separate from, and in addition to, any other Geo- or EarthCache awards program.

A current list of approved ColdCache sites can be found on the “IATCC Bookmark List”.  More information on the Ice Age Trail Atlas, the Companion Guide, the ColdCache Project and Awards Program can be found on the “ColdCache Webpage”  

DNR Permission

1.    You will pass post #4 which is on top of a drumlin.  Which direction is the steep, wide end?  Which direction is the gradual, narrow end?

2.    At post #7, you will be on top of another drumlin and you will see that the trail splits.  Are you at the steep, wide end; or the gradual,narrow end?  What direction are you facing if you look approximately halfway between the split?

3.    Based on the above information, what direction did the glacier flow in this area?
