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 ...

Slow erosion without creep in the McMurdo Dry Valleys, Antarctica
Dan Morgan, Vanderbilt University
Quantifying erosion rates is central to understanding how landscapes evolve through time and for discerning the links between landforms and the processes that shape them. The alpine valleys of the McMurdo Dry ...

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 ...

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 ...

A 54-year record of sediment yield linked with proglacial sedimentary dynamics
Martin Geilhausen, Zurich University of Applied Sciences
Proglacial zones are newly formed landscapes in front of or just beyond the outer limits of glaciers (fig. 1). They are out of equilibrium with the current climate and therefore highly sensitive to climate change. ...

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 ...

Suspended sediment yield from an Alpine proglacial zone - quantification and controls
Martin Geilhausen, Zurich University of Applied Sciences
Proglacial zones are newly-formed landscapes in transition from glacial to non-glacial conditions which are located in front of or just beyond the outer limits of glaciers. In the context of climate change and ...

How do hydrograph recession rate and vegetation influence the morphology of point bars in sand-bed channels?
Megan Kenworthy, Center for Ecohydraulics Research, University of Idaho, Boise
A stream's hydrograph shows the volume of water flowing in the channel through time (Figure 1). Quantities often used to describe hydrographs include the flow magnitudes, the duration, and the rate of change ...

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, ...
