... Estuary. Because of high turbulence close to rockwalls and effective snow drifting, active scree slope can remain free of snow until the end of January ( Hétu and Vandelac 1989 ; Hétu and Bergeron 2004 ). The altitudinal gradient from the valley to the plateau is responsible for a shift from...

... in Namaqualand. Although their geomorphologic expression is similar, these sediments are lithologically and texturally distinct from the equally silicified soils, diatreme infills and hillside screes of the palaeo-weathering profile type commonly occurring between the farm Banke and the Vaalputs site...

... of mass wasting processes; this tendency reverses in colder and wetter periods. However, the treeline on the scree slopes of Mont Saint-Pierre has been extending upward from the end of the Little Ice Age until 1950. Since then, geomorphic processes have increasingly fragmented the treeline despite...

... scree accumulations are more common near the outlets of arroyos and occupy a greater fraction of large arroyos than of small ones. Small fan-shaped accumulations of fresh talus at the foot of slope beneath rills suggest that granular flows may transport sediment across the scree aprons to channels...

... convolute beds and abundant imprints of unidentifiable tree logs. No evidence of glaciogenic processes have been found in this succession, in the form of either pavement or clasts striations. The breccia and diamictite are interpreted as scree and mass-flow deposits, respectively. Along with the age...

...) revealed declines in weight and quantity of land crabs, weight of gastropod fragments, and body size of parrotfish. The Lucayan population in the Bahamas was destroyed by disease and kidnapping into slavery by the early 1500s CE; indeed, the human population of what is now the Bahamas declined from...

... m (west). The unstable slope material consists of very heterogeneous loamy scree and glacial till, which is mainly comprised of silty and clayey material as well as glacial components of varying size from the surrounding bedrock. The bedrock basement consists of layered upper cretaceous marls...

... decades the spatial resolution ( i.e. the pixel size) of the Earth observation satellites has considerably improved. In the case of a pixel size comprised between 100 and 1000 m, the resolution of the satellite is low or moderate, and very low beyond 1000 m (geostationary satellites only). This range...

... basal lithic tuffs and graded fiamme swarms. These sheets are interpreted as moderately to densely welded rhyodacite ignimbrites (25–100 m thick). A steep body of fragmented (fiamme-bearing) rhyodacite with intrusive non-fragmented contacts is interpreted as an ignimbrite vent system. The rhyodacite...

... sandstones is wedge-shaped (1.5 to 7.7 m thick and 7.7 to 76.2 m wide) and contains some root marks, abundant plant fragments, and coaly chips ( Fig. 8 ). Other stratigraphic cross sections of equivalent middle-upper Haymond Formation show significantly different lateral and vertical variations...

... ). Floodplain facies occurs stratigraphically higher in the GLOF cycle. A glacial outburst event raised the water level by hundreds of meters, releasing immense floods down the valley floor and valley sides. Angular rock fragments were trapped by flood currents from valley sides. Cobble-sized rock fragments...

... and charcoalified wood fragments are present ( Figure 4G ), but poorly preserved ( McLachlan and McMillan, 1976 ; Shone 1976 ). Unfortunately no diagnostic age or positive identification can be made from these fossils ( McLachlan and McMillan, 1976 ). Sedimentary characteristics (coarse clast sizes, massive...

Macrofossils commonly weather out from poorly consolidated mudstones and subsequently lie loose on the surface of scree-covered mountain slopes. However, the locality of Bohemanflya in the Isfjorden area (Fig. 2 ) provided favourable sampling conditions...

... FA is intersected and generally overlain by ripple facies (FA 4 and 5). In Kampesteindalen it is overlain by a marine transgressive bed. Soft sediment deformation structures are seen as overturned foresets, convolute bedding, slumped beds, water-escape structures and conical-shaped zones of deformed...
