Radiocarbon calibration
Quan Hua
Radiocarbon dating is one of the most reliable and well-established methods for dating the Holocene and Late Pleistocene. Natural radiocarbon or 14C is produced in the atmosphere by the interaction of the secondary ...

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 ...

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 ...

Stream response to Climate Change, Atacama Desert, Chile
Jason Rech, Miami University-Oxford
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 ...

Constraining the timing of soil formation in linear dunes: A case study from the Strzelecki and Tirari Deserts, central Australia
Kathryn Fitzsimmons
Desert dune formation can be episodic. The intensity of aeolian activity varies in response to environmental conditions, including concentrated reworking events and periods of prolonged partial activity. Buried ...

The influence of volcanism on Andean Rivers
Scott Hynek
The Andean Cordillera spans more than 60° of latitude along the western margin of the South American continent. The climate, tectonics, and morphology of the range are known to vary considerably and predictably ...

Surficial carbonate and land surfaces of the Pamir Plateau, Tajikistan
Scott Hynek
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, ...

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 ...

Marine terraces in mid-latitude settings: the case of the Oregon USA coast
Harvey Kelsey
Marine terraces are terraced landforms that occur as elevated flats inboard of, and parallel to, coastlines. Outstanding examples of a stair-step landscape of marine terraces can be found in many places in the ...
