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 ...

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 ...

Uncovering Details of Glacial History by the Marks Left on the Land
Twila Moon, University of Washington-Bothell Campus
Glaciers can be thought of as large rivers of ice. One of the key elements that separates a glacier from an ice field is that a glacier more actively moves through the landscape, the mechanical properties of the ...

Development of Palimpsest Landscapes
Jasper Knight
In Physical Geography, a palimpsest landscape is one where, in any given region, the different landforms that make up the landscape are not of the same age, with some surface landforms being very young because they ...

Erodibility, tensile strength, and the "k" problem in Grand kanyon
Natalie Bursztyn, University of Montana
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 ...

The influence of weathering and soils on the geomorphic expression of tectonic landforms: an exception to a rule of tectonic geomorphology
Martha Eppes, University of North Carolina at Charlotte
Background – Blind Thrust Faults and Seismic Hazard In southern California, one of the most tectonically active regions of the United States, it is critical to understand the potential earthquake hazard that ...

Quaternary glaciation of the Himalaya and Tibet
Lewis Owen, North Carolina State University
The mountains of the Himalaya and Tibet are the most glaciated regions outside of the polar realm. The countries within and bordering the Himalaya and Tibet depend greatly on the glacial and associated hydrological ...

Fire geomorphology: Fire-related erosion helps to shape our landscapes
Kerry Riley
The frequency of large wildfires has increased on all vegetated continents (Bowman et al., 2009). Wildfires can have profound influences on erosion rates, particularly in steep mountain basins. Fire-related ...

A new deglacial chronology of the Laurentide Ice Sheet in Wisconsin
David Ullman, University of Wisconsin-Madison
During the past 2.5 million years, the earth has seen a series of major ice sheets built through the slow accumulation of snow, followed by warming and rapid ice collapse. This fluctuation in global ice sheets is ...

The retreat chronology of the Laurentide Ice Sheet during the last 10,000 years and implications for deglacial sea-level rise
David Ullman, University of Wisconsin-Madison
Much of the world's population is located along the coasts. In a world of changing climate, the rate of sea level rise will determine the ability of these communities to adapt to sea level rise. Perhaps the ...
