Little bump on the prairie

Little bump on the prairie

A small glacial kame rises above the surrounding flatland at Moraine Hills State Park near McHenry, Illinois. A foggy morning helps to define the contours of the kame against the wooded backdrop -- I had been to the park several times and never really noticed this formation until this day.

Kames are formed by the flow of water through a narrow tunnel in a melting glacier. Dirt and debris form piles at the bottom of the glacier and are revealed as the glacier recedes. Kames can be the dominant feature in a post-glacial landscape.

So in this instance, it kame, it thawed, it conquered. Ba-dum.
