Cliff

cliffscragprecipice
Scree is a collection of broken rock fragments at the base of crags, mountain cliffs, volcanoes or valley shoulders that has accumulated through periodic rockfall from adjacent cliff faces.
Most cliffs have some form of scree slope at their base.

Rockfall

Scree is a collection of broken rock fragments at the base of crags, mountain cliffs, volcanoes or valley shoulders that has accumulated through periodic rockfall from adjacent cliff faces.
The pieces of rock collect at the bottom creating a talus or scree.

Debris

wreckagecoarsedebris flow
Talus deposits typically have a concave upwards form, while the maximum inclination corresponds to the angle of repose of the mean debris size.
When it accumulates at the base of hillsides, it can be called "talus" or "scree".

Angle of repose

the maximum possible sand slopean engineering termcritical angle of repose
Talus deposits typically have a concave upwards form, while the maximum inclination corresponds to the angle of repose of the mean debris size.
It can also be used in determining whether or not a slope (of a stockpile, or uncompacted gravel bank, for example) will likely collapse; the talus slope is derived from angle of repose and represents the steepest slope a pile of granular material will take.

Weathering

Formation of scree or talus deposits is the result of physical and chemical weathering and erosion acting on a rock face.
Severe frost shattering produces huge piles of rock fragments called scree which may be located at the foot of mountain areas or along slopes.

Erosion

Formation of scree or talus deposits is the result of physical and chemical weathering and erosion acting on a rock face.
One of the visible topographical manifestations of a very slow form of such activity is a scree slope.

Lech dl Dragon

For example, Lech dl Dragon, in the Sella group of the Dolomites, derives from the melting waters of a glacier, hidden under a thick layer of scree.
It is created periodically from the melting of a glacier that is hidden beneath the scree from the rock towers, above.

Old Norse

The term scree comes from the Old Norse term for landslide, skriða, while the term talus is a French word meaning a slope or embankment.

Climate

The predominant processes that degrade a rock slope depend largely on the regional climate (temperature, amount of rainfall, etc.).

Joint (geology)

During the day, water can flow into joints and discontinuities in the rock wall.

Frost weathering

freeze-thawfrost actionhydrofracturing
Freeze-thaw scree production is thought to be most common during the spring and fall, when the daily temperatures fluctuate around the freezing point of water, and snow melt produces ample free water.

Frost heaving

Many argue that frost heaving, like that known to act in soil in permafrost areas, may play an important role in cliff degradation in cold places.

The mountain has been significantly eroded by glaciers over the last 25,000 years, and is now covered in talus deposits.

Sonorella

They are known commonly as talussnails or talus snails because most live in talus and similar habitat.

Cardenas Basalt

The lower part of the Cardenas Basalt forms granular talus slopes.
