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 ...

Sinkhole hazard above salt, Dead Sea shore
amos frumkin
The hazard of sinkholes (collapse dolines) is commonly associated with karst (landscapes dominated by dissolution and subsurface drainage), where subsurface cavities undermine the overlying strata, causing ...

The Kern River, California: A Story of Uplift, Incision, and Flood Control
Natalie Bursztyn, University of Montana
Within Kern County, the present day Kern River is an example of two distinct river environments. In the Sierra Nevada, the Kern River is in a classic V-shaped canyon (Fig. 1) as it erodes towards base level. In ...

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 ...

Soils, relict landscapes and paleoclimate in the Atacama Desert, Chile
Jason Rech, Miami University-Oxford
The exceptionally dry Atacama Desert, adjacent to the Central Andes in northern Chile, contains many relict landscapes (landscapes formed in the past, but preserved on the present surface; Figure 1). One remarkable ...

Stream response to Climate Change, Atacama Desert, Chile
Jason A Rech, Craig Tully, Claudio Latorre Miami University, Ohio; Pontificia Universidad Católica de Chile
Climate on earth is constantly changing. Earth's climate can change gradually over millions of years (tectonic-scale) due to changes in greenhouse gases or the slow movement of tectonic plates, or climate can ...

Arroyo Cutting in the Southwestern U.S.
Jonathan Harvey
Introduction In the semiarid southwestern United States, water is extremely important. However, most streams in the region are ephemeral, meaning that they are dry for much of the year and flow only during flash ...

Linear dune formation: Longitudinal elongation or local wind rifting? An example from the Strzelecki Desert, central Australia
Kathryn Fitzsimmons
The Australian desert dunefields are dominated by linear dunes, which form a large anti-clockwise whorl across more than one third of the continent (Wasson et al., 1988). Despite being so extensive, the mechanisms ...

The continental dunefield of Australia
Paul Hesse
Dunefields cover a large portion of the Australian continent in areas with favourable topography, climate and sand supply. The main areas of dunes lie in a diagonal band across the continent from the Mallee ...

Salt Karst: Mount Sedom diapir
amos frumkin
A unique, rapidly evolving karst landscape is described below. It develops on salt rock (halite) at such a rate that a human lifetime is enough to observe considerable geomorphic variations. Halite is the most ...
