We examined the distribution of ground-flora species (herbaceous and woody species <1 m tall) across riparian areas of northeastern Wisconsin in an effort to understand how hierarchical landscape properties, such as the physiographic system (ground moraine and outwash plain), valley system (constrained and unconstrained), and valley floor landforms influence distribution patterns of ground-flor...

Introduction Glacial erratic boulders are plucked from bedrock by flowing ice, transported in the direction of ice flow, and deposited at the terminus of the glacier. If derived from a localized, distinctive region of bedrock, glacial erratics may be used as indicator stones to map the direction of ice flow. Furthermore, glacial erratics evolve during transport, becoming smaller and more rounde...

There are still many uncertainties about the climatic forcing that drove glacier fluctuations of Patagonian Ice Sheet (PIS, 38–55°S) during last glacial period. A key source uncertainty is asynchrony ice lobe between northern, central, and southern PIS. To fully understand regional trends requires careful mapping extensive geochronological studies. This paper presents geomorphological reconstru...

| In this paper, we use single and dualpass satellite-based interferometric radar to measure the ow magnitude of a large alpine glacier. Since the radar measurements alone are not su cient to resolve the 3-D ow direction of the glacier, several ow directions assumptions are made, and checked for mutual consistency. The assumptions that the horizontal component of ow is parallel to the medial mo...

We develop numerical solutions of a theoretical model which has been proposed to explain the formation of subglacial bedforms. The model has been shown to have the capability of producing bedforms in two dimensions, when they may be interpreted as ribbed moraine. However, these investigations have left unanswered the question of whether the theory is capable of producing fully three‐dimensional...
