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.

Native animals and the formation of healthy soils
David Eldridge
Soil is an important resource on which most of the world's production depends. Soil is not an inert medium; it is a living and breathing ecosystem made up of water, air and organic material. Soil provides the ...

Ant activity and the development of nutrient-rich soil profiles
David Eldridge
Rainfall is one of the most important factors in arid and semi-arid (dryland) environments; it supplements soil moisture storage, stimulates plant germination, and brings new life to dormant vegetation. Rainfall ...

Influence of Dam Operations on Geomorphology and Sediment in the Colorado River corridor, Grand Canyon National Park, Arizona
Amy Draut
Large dams can greatly alter the physical and biological environments of rivers, by changing the magnitude and timing of flows, sediment transport, and water temperature. One of the most iconic landscapes in the ...

Erodibility, tensile strength, and the "k" problem in Grand kanyon
Natalie Bursztyn, Utah State University
River profile shape is an important indicator of the geomorphic processes and history that contributed to its modern form. In the case of bedrock streams during episodes of incision, resistance of river-level ...

Sinkhole hazard above salt, Dead Sea shore
amos frumkin
The hazard of sinkholes (collapse dolines) is commonly associated with karst (landscapes dominated by dissolution and subsurface drainage), where subsurface cavities undermine the overlying strata, causing ...

Salt Karst: Mount Sedom diapir
amos frumkin
A unique, rapidly evolving karst landscape is described below. It develops on salt rock (halite) at such a rate that a human lifetime is enough to observe considerable geomorphic variations. Halite is the most ...

The Kern River, California: A Story of Uplift, Incision, and Flood Control
Natalie Bursztyn, Utah State University
Within Kern County, the present day Kern River is an example of two distinct river environments. In the Sierra Nevada, the Kern River is in a classic V-shaped canyon (Fig. 1) as it erodes towards base level. In ...

Challenges associated with investigations into the geomorphology of other worlds: A case study examining glacier-like forms in the mid-latitudes of Mars
Colin Souness
Ever since global imagery of Mars was first gathered and transmitted back to Earth in 1971 by the Mariner 9 orbiter, geomorphologists have remarked upon the abundance of landforms which seem to suggest the action ...

Using geomorphology to determine tectonic slip at Wallace Creek
Sarah Robinson, United States Air Force Academy
The Carrizo Plain along the San Andreas fault in California is world-famous for its dramatic offset features. Sag ponds, linear ridges, beheaded channels and scarps define the landscape along the fault (Vedder and ...

The degradation of glacial deposits in the McMurdo Dry Valleys, Antarctica
Dan Morgan, Vanderbilt University
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 ...
