Editing Scree (section)

==Description==
Talus deposits typically have a concave upwards form, where the maximum inclination corresponds to the [[angle of repose]] of the mean debris particle size.<ref name=TurnerSchuster1996/>

Scree slopes are often assumed to be close to the angle of repose. This is the slope at which a pile of granular material becomes mechanically unstable. However, careful examination of scree slopes shows that only those that are either rapidly accumulating new material, or are experiencing rapid removal of material from their bases, are close to the angle of repose. Most scree slopes are less steep, and they often show a concave shape, so that the foot of the slope is less steep than the top of the slope.<ref>{{cite journal |last1=Statham |first1=I. |title=Scree Slope Development under Conditions of Surface Particle Movement |journal=Transactions of the Institute of British Geographers |date=July 1973 |issue=59 |pages=41–53 |doi=10.2307/621711|jstor=621711 }}</ref><ref>{{cite journal |last1=Statham |first1=Ian |title=A scree slope rockfall model |journal=Earth Surface Processes |date=January 1976 |volume=1 |issue=1 |pages=43–62 |doi=10.1002/esp.3290010106}}</ref>

Scree with large, boulder-sized rock fragments may form [[talus cave]]s, or human-sized passages formed in-between boulders.<ref>{{cite web |title=Talus Caves - Caves and Karst (U.S. National Park Service) |url=https://www.nps.gov/subjects/caves/talus-caves.htm |website=www.nps.gov|publisher=National Park Service |access-date=16 July 2024 |language=en}}</ref>
