Geomorphology Vignettes

These illustrated essays have been contributed by participants in the Teaching Geomorphology in the 21st Century workshop in 2008. The vignettes are drafts that are being written and revised by the participants and are not finished products.

Using technology as an aid to the geomorphologist
Sarah Robinson, Arizona State University at the Tempe Campus
Geomorphology requires characterization of the earth's surface at sufficient high resolution in 3 dimensions to explicitly represent landforms. Measuring change requires repeat survey, thus adding the 4th ...

Using geomorphology to determine tectonic slip at Wallace Creek
Sarah Robinson, Arizona State University at the Tempe Campus
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 ...

Glacial Features of Franconia Notch, New Hampshire
R. Laurence Davis, University of New Haven
INTRODUCTION Franconia Notch, New Hampshire (Figure 1) is a classic northern Appalachian glaciated valley. It has geomorphic features from pre-glacial times, from the glaciation itself, from glacial meltwater, and ...

Karst Processes and Landforms on San Salvador Island, Bahamas
R. Laurence Davis, University of New Haven
INTRODUCTION San Salvador Island is located in the Central Bahamas, about 225 km ESE of Miami and is about 12 km north to south and about 5 km east to west (Figure 1). It is notable for being Columbus' first ...

Geomorphic history controls the locations of fresh-water wetlands on barrier islands, Virginia's Atlantic shore
Rich Whittecar, Old Dominion University
Fresh-water ponds on low sand islands Native Americans, pirates and the early European colonists used them. Ship-wreaked sailors owe their survival to them. Fresh-water ponds somehow seem out of place, though, ...

Plateau Glaciers and their significance
Brian Whalley, niversity of Sheffield
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 ...

Volcanic History and Cinder Cone Erosion at Newberry Volcano, Oregon
Steve Taylor, Western Oregon University
Surface landforms result from a balance of constructional and erosional processes operating at geological time scales of 102 to 105 years. The landscape evolves over time as masses of earth material are transferred ...

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 ...

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 ...

The Kern River, California: A Story of Uplift, Incision, and Flood Control
Natalie Bursztyn, The University of Montana-Missoula
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 ...
