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 ...

Rock glaciers: their ice and debris balances
Brian Whalley, niversity of Sheffield
Rock glaciers are best defined by their topography (Fig. 1) and that they flow slowly. Their dynamic character is attributed to the flow of ice deforming the associated weathered rock debris. Typically, they flow ...

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 ...

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 ...

Uplift rates and vertical fault displacements derived from marine terraces, Crete, Greece
Sean Gallen, Colorado State University
Introduction: Long-lived and continuing uplift and pervasive extensional faulting are a testament to the active tectonics of the island of Crete, located in the eastern Mediterranean (Figure 1). Large earthquakes ...

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 ...
