Interesting landforms created by an ancient network of earthworks are shown, using Google satellite imagery enhanced by an image processing. This network covers a large part of the land near the Titicaca Lake. Satellite images clearly display the slopes of hills criss-crossed with terrace walls and the surfaces of the plains covered with raised fields, indicating that this was once a highly pro...

Introduction: The recognition of groups of terrestrial climate-related landforms has led to the definition of different morphogenetic regions [e.g., 1-2] which have been classified in terms of both mean annual temperature and precipitation. Marchant and Head (2007) [3] used this approach to classify the McMurdo Dry Valleys of Antarctica (ADV) into three separate microclimate zones based on grou...

The Antarctic Dry Valleys (ADV) are generally classified as a hyper-arid, cold-polar desert. The region has long been considered an important terrestrial analog for Mars because of its generally cold and dry climate and because it contains a suite of landforms at macro-, meso-, and microscales that closely resemble those occurring on the martian surface. The extreme hyperaridity of both Mars an...

Abstract The period 1965–2000 saw a sustained increase in research and publications on fluvial processes landforms. trend towards generalization and/or mechanistic understanding, rather than site-specific history, continued. Research was multidisciplinary, with important contributions from hydraulic engineers, geologists physical geographers experimental theoretical approaches as well geomorpho...

Extensive evidence of landform-scale martian geomorphic changes has been acquired in the last decade, and number range examples surface activity have increased as more high-resolution imagery acquired. Within present-day Mars climate, wind frost/ice are dominant drivers, resulting large avalanches material down icy, rocky, or sandy slopes; sediment transport leading to many scales aeolian bedfo...

Abstract The Nullarbor Plain is a ~200,000 km 2 planar karst surface in southern Australia, underlain by Cenozoic shallow‐water limestones. During the Miocene area was uplifted, and although plain generally considered extremely flat, locally, geomorphology of retains evidence earth processes across long, middle Miocene‐to‐present time span. accessibility recent 0.4 arc‐second TanDEM‐X digital e...
