E71: I need to archive this EC due to the fact is I no longer own this pit. The new owners plan to excavate this area out so this spot will be here no longer.

Please be careful this is an active pit with a lot of truck traffic in the summer. Short climb up a wooded hill side to the top of an Esker. Terrain may be slippery if wet or after rain fall or if snow covered.
An esker is a sinuous, narrow, steep-sided ridge made up of sand and gravel formed in a melt water tunnel under a glacier. The last glacial ice sheet across Michigan ended approximately 12,000 years ago. Eskers were created by glacial melt water and tend to meander across the earth's surface and resemble drainage patterns of rivers and streams today. A glacier collects materials from rivers of glacial melt water under the ice. When the glacier melts, the material which remains in the underground river forms an esker. Eskers usually contain sand and gravel. The thickness of the sediments vary and depend mostly on the nature of the melt water flow. Areas of high flow show larger sediments than areas of slower flows. Dimensions vary greatly. They range in length from less than a mile to nearly 100 miles long. This esker meanders across the landscape for more than 3 miles from the North side of Douglas Lake to these posted cords. Eskers are often used for construction of highways. This is the beginning of the esker and is a small example for a better understand of what an esker actually looks like and what it is made up of.
To log this earthcache, you must complete 4 tasks at the posted cords:
1) DESCRIBE THE CROWN OF THE ESKER. Describe the width and the crown of the esker top, and the elevation.
2) ESTIMATE THE WIDTH OF THE ESKER BASE.
3) DESCRIBE THE UNIQUE MAN-MADE ROCK FORMATION.
Send the above information to the Earthcache owner by e-mail.
4) BRING YOUR CAMERA. We would like a photo of your team with your GPSr Please upload your photo(s) with your "found it" log. (pic optional of course)
