When I was in college, I took a course on physical geography as part of my general education requirements. Our course textbook covered various unique and interesting natural areas in the United States ranging from the canyon lands of Utah to the limestone caves of Kentucky, and we learned about the specific geographic confluences that formed these natural wonders. One day my classmates and I were bemused to find that we were studying glacial features in the exotic locale of Southeastern Wisconsin. Having lived in the area most of my life, I never really thought of kettles, eskers, moraines, and drumlins as being anything particularly special, but apparently, these features that formed as giant sheets of ice retreated across the landscape are relatively rare in the topography of the world, and we're lucky to have them.
