An unusual geologic feature of the Loess Hills is the occurrence of parallel, step-like terraces carved into the slopes like a stairway. These terraces are referred to as cat steps, and their origin is somewhat uncertain. They are most likely the result of a geological process in which the loess slumps downward when it becomes extremely wet. However, cattle grazing has occurred in most of the hills for over 100 years, and it is possible that the preference of cattle to follow these natural steps has enhanced their appearance.
