This lesson is a demonstration in how geological layers form and erode using just a stack of towels. The author describes this lesson as GeoArt, which means one looks at geologic processes through both a scientific and an artistic lens.

Explains what standing rocks are, how they are formed by erosion, and gives the names of some well-known ones in Indiana.
