The posted coords will bring you to an intersection near a roadside anomaly we are only allowed to appreciate from afar. As you approach this point, please take time to notice the surrounding terrain.
Flat. Yep...plain ol' flat as far as the eye can see, except for those two funny hills over there...
The “Flat” terrain you are surveying is an “outwash plain” left behind as a result of the last glacier, the Des Moines Lobe, melting it's way out of the the neighborhood 12,000 years ago. An outwash plain is the broad-based depositional field of debrise (till, sand and gravel, etc.) as a result a glacier melting down faster than it's advance. The debrise is no longer suspended in the ice and just settles upon the landscape, creating the sandy, gravely soil you see today.
The two “funny looking hills” off to the southwest are actually two different types of “kames.”
A Kame is a big pile of glacial meltdown debrise deposited in one area creating a round, conical shaped hill The other type of Kame-form observed here is a “camel back” kame, which is several kames being deposited simultaneously in a small grouping, forming more of a ridge with individual terminus points marking the top of each “pile of Kame.” A quick referral to the topo map or terrain map of this area will clearly display the differences in deposits.
To log this Roadside Geological Glacial Anomaly, please forward in an email:
1.Your estimate of the height of these Kames. Please reference your unit of measurement.
2.How many individual deposits went into creating the single camel back kame? (The details may be more readily appreciated when viewed from a topo or terrain map.)
and.....
3.Please post a photo of you or your Gps with the Kame Complex in the background.
Thank you for taking the time to appreciate this quick lesson in Doc.'s Roadside Geology 101.
