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 ...

Land disturbance and recovery following a massive deforestation event in the Missouri Ozarks
Winston Crausaz
In 1983 California businessman Raymond L. Sheeks purchased 40 square kilometers of wooded upland in the Ozark Mountains of south-central Missouri. Starting with steep forested slopes, a relief of 100 meters, thin ...

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 ...

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 ...

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 ...

Cold climate conditions as a driver of alluvial fan deposition in the Lost River Range, Idaho, USA
Megan Kenworthy, Center for Ecohydraulics Research, University of Idaho, Boise
Numerous large alluvial fans sit along the western front of the Lost River Range (LRR) in east-central Idaho, USA (Figure 1). These alluvial fans form where streams exit confined basins within the mountain range, ...

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 ...

Beach replenishment on developed shorelines: a coupled human–landscape system
Eli Lazarus
Beach replenishment (also called "beach nourishment") is an engineering strategy commonly used on sandy shorelines where erosion threatens coastal property and infrastructure. The process involves ...
