Framework / Assessment USDI Indicators of Rangeland Health (2000) Summary Pedestals and terracettes are important indicators of the movement of soil by water and/or by wind. Pedestals are rocks or plants that appear elevated as a result of soil loss by wind or water erosion. Pedestals can also be caused by non-erosional processes such as frost heaving or through soil or litter deposition on and around plants, thus it is important to distinguish and not include this type of pedestalling as an indication of erosional processes.
