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 ...

Cracking up: emerging evidence for the importance of the sun in the mechanical weathering of rocks
Martha Eppes, University of North Carolina at Charlotte
Introduction Physical weathering, through the breakdown of rock into sediment, plays a fundamental role in the rock cycle and potentially a key role in landscape evolution. In addition, the physical breakdown of ...

Defining rates of erosion using terrestrial cosmogenic nuclides in the Himalaya
Lewis Owen, North Carolina State University
The Himalaya and Tibet comprise the greatest mountain mass on our planet, stretching for ~ 2000 km east-west and >1500 km north-south with an average elevation of ~5000 m above sea level. The mountain mass ...

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 ...

Great Basin Dunes and Winds: What Might They Tell Us About the Geologic Record?
Paul Jewell, University of Utah
Dune fields have long been recognized as important geomorphic features of continents, both on the modern Earth and in the geologic record. While dunes can exhibit a variety of morphologies (McKee, 1979), they ...

Geomorphic Setting & Archaeology of the Cunene River, Namibia
Kathleen Nicoll, University of Utah
Introduction This vignette presents a virtual tour of the Cunene River, and a prehistoric archaeological site located on a fluvial terrace in northern Namibia. Today the Cunene River is an important transnational ...

Living on a slippery slope: Case studies of geologic hazards from the Wasatch Front, Utah
Kathleen Nicoll, University of Utah
Throughout their history, humans have fought the natural elements; we build shelters, roads, hospitals and malls wherever we can engineer "solutions" and strategies that permit us to thrive, even in harsh ...

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 ...
