Lake Bonneville Spits as Paleoclimate Wind Socks part of Vignettes:Vignette Collection
Lake Bonneville is the largest of several pluvial lakes (formed during a period of elevated precipitation) that formed in the Great Basin of the western United States during the Last Glacial Maximum 32,000 to ...

Soils, relict landscapes and paleoclimate in the Atacama Desert, Chile part of Vignettes:Vignette Collection
The exceptionally dry Atacama Desert, adjacent to the Central Andes in northern Chile, contains many relict landscapes (landscapes formed in the past, but preserved on the present surface; Figure 1). One remarkable ...

Great Basin Dunes and Winds: What Might They Tell Us About the Geologic Record? part of Vignettes:Vignette Collection
Dune fields have long been recognized as important geomorphic features of continents, both on the modern Earth and in the geologic record. While dunes can exhibit a variety of morphologies (McKee, 1979), they ...

Vignettes part of Vignettes
Vignettes are stand-alone, illustrated electronic case studies that teach about geomorphology, surface processes, and/or Quaternary history. Vignettes can be used alone or in combination with the "Key ...

Spatial and temporal geomorphic variability in fluvial systems: A case study from the Conejos River, Colorado part of Vignettes:Vignette Collection
Effective and sustainable river management requires an understanding of how fluvial processes vary both spatially and temporally (e.g. Wohl et al., 2005). This is important because rivers are capable of alternating ...

The retreat chronology of the Laurentide Ice Sheet during the last 10,000 years and implications for deglacial sea-level rise part of Vignettes:Vignette Collection
Much of the world's population is located along the coasts. In a world of changing climate, the rate of sea level rise will determine the ability of these communities to adapt to sea level rise. Perhaps the ...

The pattern and timing of the last Pleistocene glaciation in northeastern Utah: evidence of an ancient lake effect part of Vignettes:Vignette Collection
Setting During the last Pleistocene glaciation, the highest mountains in northern Utah were blanketed by snow and ice, accumulating in broad cirques to form valley glaciers. The Great Salt Lake rose more than 300 ...

Plateau Glaciers and their significance part of Vignettes:Vignette Collection
Plateaus exist in many mountainous parts of the world. Although not as spectacular as high, prominent peaks, they do often have (or have had in the past) glaciers associated with them. In this vignette I describe ...

Reconstructing Late Quaternary paleoenvironments in the eastern Bolivian lowlands – approaches and results. part of Vignettes:Vignette Collection
The reconstruction of present and past environmental dynamics is a key issue in the ongoing discussion of global change. In South America for a long time most paleoenvironmental and paleoclimate studies came from ...

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 ...
