Rockfall

The relatively free falling or precipitous movement of a newly detached segment of bedrock (usually massive, homogeneous, or jointed) of any size from a cliff or other very steep slope; it is the fastest form of mass movement and is most frequent in mountains during spring when there is repeated freezing and thawing of water in cracks in the rock. Syn: sturzstrom Neuendorf, K.K.E., Mehl, J.P., Jr., and Jackson, J.A., eds., 2011, Glossary of Geology: Alexandria, Virginia, American Geological Institute, 799 p.
