Landscape response in the California Coast Ranges to the stormy conditions of the Pleistocene to Holocene climatic transition
Antonio Garcia
Introduction: temporal scales, spatial scales, climate, and tectonics A long-standing problem in geomorphology is identifying the relative roles of climate and tectonism on landscape evolution. Here we examine the ...

Rivers crossing growing folds
Douglas Burbank
The interactions of fluvial systems with active deforming landscapes has provided fertile ground for exploration of the adjustments that rivers make when they are perturbed by deformation. Two ingredients are ...

Denudation rate chronologies and the topographic development of the San Bernardino Mountains, California
William Phillips
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 ...

Eolian Landforms and Deposits of the Eastern Snake River Plain, Idaho
William Phillips
The Eastern Snake River Plain (ESRP) is a northeast-trending, 300 kilometer-long depression underlain by Cenozoic volcanic rocks (Fig. 1). Well-known for many examples of volcanic landforms including basalt lava ...

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 ...

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 ...

Fluvial terrace history, Kings Creek, Manhattan, Kansas
charles oviatt
Natural cutbank exposures along streams can provide information about the geomorphic history of the stream valley. In a fluvial system, extrinsic factors, such as climate, tectonics, or land use, can lead to ...

The Snowplow, Lake Bonneville, Utah
charles oviatt
Lake Bonneville was the largest of the late Pleistocene lakes in the Great Basin of western North America (Fig. 1). It occupied the basin of modern Great Salt Lake and was hydrographically closed during its ...

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 ...
