The Mexican Alps: A Zone of Glacier Carved Cirques and Valleys
Winston Crausaz
BACKGROUND The Mexican Alps is a zone of spectacular landforms similar to those found in the glaciated regions of the Rocky Mountains. It is located just north of Mexico's highest mountain, Pico de Orizaba, ...

Natural Storm Variability in New England
Adam Parris
Why storms? Climate is the long-term average of variables in the Earth's atmosphere, such as temperature, precipitation, and wind. For millions of years, climatic events, such as rainstorms, have shaped the ...

Holocene landscape evolution of alpine areas in the southern San Juan Mountains, Colorado
Brad Johnson, Appalachian State University
Alpine landscapes that were glaciated during the Last Glacial Maximum are filled with landforms which are often confusing and difficult to understand. Yet, many researchers are drawn to researching problems in ...

Some useful Non-dimensional Numbers in Geomorphology and the Art of Deriving New Ones
Nikki Strong, University of Minnesota-Twin Cities
Units of Measure One can express physical quantities in terms of many different units of measure and a particular quantity can take on very different numerical values under different unit systems. For example, ...

Surficial carbonate and land surfaces of the Pamir Plateau, Tajikistan
Scott Hynek, University of Utah
The Pamir plateau is a prominent physiographic feature in Central Asia (Figure 1). The geomorphology of the plateau interior is a result of its geologic setting and its climate. The Pamir plateau is surrounded by ...

How to reconstruct past debris flows using tree rings
Michelle Bollschweiler
1. What is a debris flow and what are the associated problems? Debris flows are a type of mass movement involving rapid transport of water and saturated material (sand, mud, blocks, organic matter, ...) down steep, ...

Glacier Fluctuations Since the Last Glacial Maximum in Southwest Alaska
Jonathan Harvey
Glacier fluctuations since the last glacial maximum in southwest Alaska Introduction During the last glacial maximum (LGM), alpine glaciers in the western cordillera expanded, coalesced, and flowed onto ...

Denudation rate chronologies and the topographic development of the San Bernardino Mountains, California
William Phillips, University of Idaho
How does the topography of mountains develop? What roles do crustal processes such as faulting and surface processes such as erosion play? These questions have long been a focus of geomorphic research. In the past ...

Climate change in the dead heart of Australia
Joshua Larsen
Despite the absence of large-scale glaciation, the Australian continent has experienced substantial environmental change throughout the Quaternary period. This is especially pronounced in central Australia, where ...

Regional trends in desert dune morphology and orientation: Examples from the Australian deserts
Kathryn Fitzsimmons
Dunes are the major landforms within the desert regions of the world, owing largely to the dominance of wind over water as a geomorphic agent in the arid zone. Linear dunes, which form parallel to the resultant ...
