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.

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 ...

Vignette Type: Stratigraphy, Process, Chronology

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 ...

Soil-water-rock interactions I: The pediment problem
Mark Strudley
You may have not initially appreciated that piedmonts (landscapes between steep mountain masses and depositional basins) are not all covered by alluvial fans. In fact, piedmonts, along with adjoining low-relief ...

Soil-water-rock interactions II: The formation of tors in arid and semiarid environments
Mark Strudley
The prominence of bedrock edifices above essentially featureless, erosional pediment surfaces underscores the crux of the 'pediment problem' that has baffled geologists since 1877(described in the Part I ...

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 ...

Surficial carbonate and land surfaces of the Pamir Plateau, Tajikistan
Scott Hynek
The Pamir plateau is a prominent physiographic feature in Central Asia (Figure 1). The geomorphology of the plateau interior is a result of its geologic setting and its climate. The Pamir plateau is surrounded by ...

Complex interactions between channel morphology and invasive riparian plants in Canyon de Chelly, Arizona
Daniel Cadol
Ephemeral channels in the semi-arid Colorado Plateau region are subject to a cyclic process of cutting and filling resulting from variation in precipitation patterns (eg. Leopold, 1976), variation in land cover ...

Climate change in the dead heart of Australia
Joshua Larsen
Despite the absence of large-scale glaciation, the Australian continent has experienced substantial environmental change throughout the Quaternary period. This is especially pronounced in central Australia, where ...
