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 Concepts in Geomorphology", the first in a new generation of textbooks. Vignettes allow faculty to customize the learning resources they offer students to enrich and personalize student learning experiences.

Fluvial terrace history, Kings Creek, Manhattan, Kansas
charles oviatt
Natural cutbank exposures along streams can provide information about the geomorphic history of the stream valley. In a fluvial system, extrinsic factors, such as climate, tectonics, or land use, can lead to ...

The Snowplow, Lake Bonneville, Utah
charles oviatt
Lake Bonneville was the largest of the late Pleistocene lakes in the Great Basin of western North America (Fig. 1). It occupied the basin of modern Great Salt Lake and was hydrographically closed during its ...

Glacier Fluctuations Since the Last Glacial Maximum in Southwest Alaska
Jonathan Harvey
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 ...

Arroyo Cutting in the Southwestern U.S.
Jonathan Harvey
Introduction In the semiarid southwestern United States, water is extremely important. However, most streams in the region are ephemeral, meaning that they are dry for much of the year and flow only during flash ...

Soils, relict landscapes and paleoclimate in the Atacama Desert, Chile
Jason Rech, Miami University-Oxford
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 ...

Mapping erosion with glacial and fluvial sediment cooling ages in Garnet Canyon
Lisa Tranel, Illinois State University
Mountains are shaped by ice and water moving over rock surfaces and transporting sands, gravel, cobbles, and boulders away from their original source. Glaciers and streams erode rock most efficiently at different ...

Stream response to Climate Change, Atacama Desert, Chile
Jason Rech, Miami University-Oxford
Climate on earth is constantly changing. Earth's climate can change gradually over millions of years (tectonic-scale) due to changes in greenhouse gases or the slow movement of tectonic plates, or climate can ...

Constraining the timing of soil formation in linear dunes: A case study from the Strzelecki and Tirari Deserts, central Australia
Kathryn Fitzsimmons
Desert dune formation can be episodic. The intensity of aeolian activity varies in response to environmental conditions, including concentrated reworking events and periods of prolonged partial activity. Buried ...

The influence of volcanism on Andean Rivers
Scott Hynek
The Andean Cordillera spans more than 60° of latitude along the western margin of the South American continent. The climate, tectonics, and morphology of the range are known to vary considerably and predictably ...

The pattern and timing of the last Pleistocene glaciation in northeastern Utah: evidence of an ancient lake effect
Ben Laabs, SUNY College at Geneseo
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 ...
