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 ...

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 ...

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 ...

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 ...

Rock Glaciers Move Mountains - Perhaps Right Under Your Skis
Twila Moon, University of Washington-Bothell Campus
What is a Rock Glacier?A rock glacier is an geomorphic feature that includes ice and talus. An "active" rock glacier meets two important criteria: 1) it contains ice currently and 2) it is moving and ...

Human-Induced Floodplain Sedimentation in the Driftless Area of southwestern Wisconsin: Consequences on Riparian Ecosystems
Eric Booth, University of Wisconsin-Madison
The Driftless Area of southwestern Wisconsin (Figure 1) is a unique region in the Upper Midwest, USA, because it escaped the direct effects of continental glaciation. In contrast, surrounding areas have been ...

Restoration of the Elwha River system, Washington, through dam removal
Amy Draut
Most of the world's rivers contain one or more dams. On streams and rivers in the U.S. alone there are more than 75,000 dams large enough to store more than one year's runoff capacity, and many more dams ...

Influence of Dam Operations on Geomorphology and Sediment in the Colorado River corridor, Grand Canyon National Park, Arizona
Amy Draut
Large dams can greatly alter the physical and biological environments of rivers, by changing the magnitude and timing of flows, sediment transport, and water temperature. One of the most iconic landscapes in 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 ...
