This paper reviews frost‐weathering studies in the last five years and proposes key questions to be answered. New techniques have enabled us to monitor moisture contents and crack movements in near‐surface hard jointed bedrock and to evaluate seasonal rockfall activity in high mountains. Field monitoring has highlighted the roles of diurnal and annual frost cycles in controlling the timing and magnitude of frost weathering. In the laboratory, bidirectional freezing in soft, porous rocks has… 
Frost weathering of chalk
The processes and factors that determine the heave and fracture of frost-susceptible bedrock exposed to temperature cycling above and below 0°C are little known but important to understanding of rock
Environmental controls of frost cracking revealed through in situ acoustic emission measurements in steep bedrock
Frost cracking, the breakdown of rock by freezing, is one of the most important mechanical weathering processes acting on Earth's surface. Insights on the mechanisms driving frost cracking stem
Topographic and Geologic Controls on Frost Cracking in Alpine Rockwalls
Frost weathering is a major control on rockwall erosion in Alpine environments. Previous frost cracking model approaches used air temperatures as a proxy for rock temperatures to drive frost
Physical Rock Weathering: Linking Laboratory Experiments, Field Observations, and Natural Features: ─実験・観測・自然現象のリンク─
Physical rock weathering has been studied through laboratory experiments, field observations, and numerical modeling, but linking these approaches and applying the results to weathering features in
Thermal stress weathering and the spalling of Antarctic rocks
Using in situ field measurements, laboratory analyses, and numerical modeling, we test the potential efficacy of thermal stress weathering in the flaking of millimeter‐thick alteration rinds observed
The Efficacy of Frost Weathering Processes in Alpine Rockwalls
Weathering processes prepare and trigger rockfall, which is a key agent of alpine landscape evolution and a hazardous process. The relative importance of different weathering processes is hard to
Long-term frost weathering rates of limestone beach clasts, Fårö Island, Central Baltic Sea
ABSTRACT The known post-glacial isostatic land rise rates at Fårö Island, Central Baltic Sea, allowed for the reliable estimation of frost weathering rates of limestone clasts along five beach
Glacial erosion: status and outlook
Abstract Glacier-erosion rates range across orders of magnitude, and much of this variation cannot be attributed to basal sliding rates. Subglacial till acts as lubricating ‘fault gouge’ or


Direct observation of frost wedging in alpine bedrock
Width and temperature of rock joints were automatically monitored in the Japanese Alps. Three years of monitoring on a sandstone rock face shows two seasonal peaks of joint widening in autumn and
Climatic controls on frost cracking and implications for the evolution of bedrock landscapes
[1] In mountainous landscapes the role of periglacial processes in producing sediment is poorly defined, despite evidence of abundant talus slopes. Ice growth in rock has long been recognized as an
Permafrost creep and rock glacier dynamics
This review paper examines thermal conditions (active layer and permafrost), internal composition (rock and ice components), kinematics and rheology of creeping perennially frozen slopes in cold
Permafrost in steep bedrock slopes and its temperature‐related destabilization following climate change
Permafrost in steep bedrock is abundant in many cold-mountain areas, and its degradation can cause slope instability that is unexpected and unprecedented in location, magnitude, frequency, and
Near-surface Thermal Profiles in Alpine Bedrock: Implications for the Frost Weathering of Rock
The rates of many processes that control rock breakdown into transportable particles are dependent upon rock temperature. In particular, frost-cracking depends largely upon the time spent within a
The rate of bedrock weathering by frost action: Field measurements and a predictive model
Shattering rate, surface temperature, moisture content, and the physical and strength properties of bedrock were measured in four rockwall sites of the Japanese Alps. Five-year observations revealed
Bedrock freeze‐thaw weathering regime in an alpine environment, colorado front range
Reduced major axis analysis is used to describe monthly temperature averages for daily maxima, minima, means and ranges at a sequence of bedrock microenvironments in the alpine zone of the Colorado
