Rock glaciers: their ice and debris balances part of Vignettes:Vignette Collection
Rock glaciers are best defined by their topography (Fig. 1) and that they flow slowly. Their dynamic character is attributed to the flow of ice deforming the associated weathered rock debris. Typically, they flow ...

A new deglacial chronology of the Laurentide Ice Sheet in Wisconsin part of Vignettes:Vignette Collection
During the past 2.5 million years, the earth has seen a series of major ice sheets built through the slow accumulation of snow, followed by warming and rapid ice collapse. This fluctuation in global ice sheets is ...

The Katahdin Esker part of Vignettes:Vignette Collection
Introduction Many landforms left by continental ice sheets owe their origin to thermal conditions at the glacier bed. Among these are thrust features1 (Moran and others, 1980); periglacial landforms dating from ...

Ocean to Ice Cap: Photo Essay part of Vignettes:Vignette Collection
Attached is a series of photographs showing a traverse of the Greenland ice sheet from its western margin at sea level, near Kangerlussuaq (formerly Sonderstrom Fjord), to the summit station at 3207m high. The ...

Dating Greenland Ice Margin Changes part of Vignettes:Vignette Collection
The Greenland Ice Sheet (Fig. 1), one of two ice sheets on the planet, and capable of raising global sea level by ~7 meters if completely melted, is changing rapidly. Concerns about global climate change ...

Glacier Fluctuations Since the Last Glacial Maximum in Southwest Alaska part of Vignettes:Vignette Collection
Glacier fluctuations since the last glacial maximum in southwest Alaska Introduction During the last glacial maximum (LGM), alpine glaciers in the western cordillera expanded, coalesced, and flowed onto ...

Lateroglacial landforms in subtropical high mountains: A case study from the Karakoram and Hindukush Mountains part of Vignettes:Vignette Collection
Lateroglacial landforms are located at the lateral margins of the glaciers and are part of the glacial landscape systems (Iturrizaga 2001). The term "lateroglacial" defines the ice-marginal areas at the ...

Factors influencing the distribution of rock glaciers in Idaho part of Vignettes:Vignette Collection
Rock glaciers are beautiful flowing lobes of rocky debris that look like glaciers (Figure 1). These amazing landforms form in many locations within alpine valleys including along valley floors, at the base of talus ...

The Use of Geophysical Analysis to Identify the Extent of Slackwater Terrace Materials part of Vignettes:Vignette Collection
The Savanna Terrace along the Mississippi River in northwestern Illinois was formed due to drainage of the Laurentide Ice Sheet (LIS) during the Wisconsin Episode Deglaciation (Figure 1). Meltwater from the LIS ...

The degradation of glacial deposits in the McMurdo Dry Valleys, Antarctica part of Vignettes:Vignette Collection
Surface deposits such as glacial moraines and tills can yield significant information about the timing, extent, and rate of environmental change on Earth. In order to correctly interpret the record of past ...
