Geocache Description:


Much of the northern half of Indiana was sculpted thousands of years ago as glaciers advanced and retreated across the area. There may have been as many as five ice sheets passing over this area during the Ice Age until the final one, the Laurentide ice sheet, advanced as far south as Indianapolis 17,000 years ago and then began a series of melting and advancing movements for the next thousand years. Left behind were striking changes in the landscape over which the ice traveled.

The glacial feature to be explored in this earthcache is the Young America flute field. This is a series of deep channels, or flutes, that were carved from east to west when the ice sheet moved in a westward direction during one of the periods of advancement.

To claim this earthcache, you will be traveling on north-south roads across the glacial flute field and stopping at three locations where you will take elevation readings, estimate the depth of one of the flutes, and make an observation to verify your find. These results should be emailed to me. These stops may be done in any order, but remember to record your data in order to be able to report your findings.

Your email to me should include these items:

A. N 40.35.503 W 086.19.070 What is the elevation at the rock (high point)?

B. N 40.35.799 W 086.19.066 What is the elevation at the bridge (low point)?

C. Subtract elevation reading B from reading A to determine the depth of the flute.

D. N 40.35.934 W 086.16.772 To verify that you have located this earthcache, find a marker at this location that warns about something underground. Tell me what is buried and be specific.

As you drive across these impressive flutes carved by a massive glacier, there are many places where you will see evidence of the power of the ice sheet that shaped the area.
