A catstep is a narrow, back-tilted terrace or bench on a grassy slope, formed when a hillside slumps beneath its own weight. Several catsteps may form together, each only a few inches in height—a staircase fit for a feline; or an individual catstep may be as high as four feet. Some of the best examples are found in the deep, wind-formed loess deposits of western Iowa. These are particularly prone to small landslides.
