Lake Bonneville Spits as Paleoclimate Wind Socks
Paul Jewell, University of Utah
Lake Bonneville is the largest of several pluvial lakes (formed during a period of elevated precipitation) that formed in the Great Basin of the western United States during the Last Glacial Maximum 32,000 to ...

Factors influencing the distribution of rock glaciers in Idaho
Brad Johnson, Appalachian State University
Rock glaciers are beautiful flowing lobes of rocky debris that look like glaciers (Figure 1). These amazing landforms form in many locations within alpine valleys including along valley floors, at the base of talus ...

Transport, retention, and geomorphic role of wood in tropical headwater streams, Costa Rica
Daniel Cadol, Colorado State University
The role of wood in shaping stream channels is an often overlooked component of the fluvial system. In forested catchments, wood is an integral part of the geomorphic and ecological function of streams. ...

Understanding the pattern of glaciations of Shaluli Shan in the southeastern Tibetan Plateau by using geomorphological mapping
Ping Fu
Geomorphological mapping at a large scale is a powerful tool in understanding the paleoglaciology of northern hemispheric ice sheets, and has recently been used in reconstructing the paleoglaciation of the ...

Dating Greenland Ice Margin Changes
Jason Briner, SUNY at Buffalo
The Greenland Ice Sheet (Fig. 1), one of two ice sheets on the planet, and capable of raising global sea level by ~7 meters if completely melted, is changing rapidly. Concerns about global climate change ...

Using cosmogenic isotopes to resolve the history of fjord glaciation
Jason Briner, SUNY at Buffalo
IntroductionIn high-latitude regions, the edges of continents are dissected with large, spectacular fjords. Although we know that fjords are deeply carved glacial valleys that have their bottoms below sea level, ...

Reconstructing hydrological events from annually laminated sediment in northwestern British Columbia
Jaclyn Cockburn, University of Guelph
Determining what has happened in a landscape in the past is a key sub-discipline in geomorphology – through various techniques, aspects of these past environments are reconstructed. For example, examining ...

Are pancakes really so flat? LiDAR and the recognition of subtle geomorphology
Ben DeJong, University of Vermont and State Agricultural College
The Delmarva Peninsula that comprises the eastern landmass enclosing the Chesapeake Bay is one of those places where you can ride a bike for long distances without changing gears at all. This landscape is ...

Spatial and temporal geomorphic variability in fluvial systems: A case study from the Conejos River, Colorado
Anthony Layzell, University of Kansas Main Campus
Effective and sustainable river management requires an understanding of how fluvial processes vary both spatially and temporally (e.g. Wohl et al., 2005). This is important because rivers are capable of alternating ...

The Geomorphological Effects of Geotextile Tubes Emplaced Along a Transgressive Coastline and Their Consequences
Richard Ashmore
Introduction The Upper Texas Gulf Coast along the Bolivar Peninsula, east of Galveston, is a transgressive coastline where the beach is currently moving landward up to several feet each year. Thus, erosion has been ...
