A geologic map is a fundamental scientific tool that shows the distribution of geologic material. This study used data gathered at Seven Mile Creek Park to make a geologic map. This data examines the relationships between ravine cutting, terrace development, and base level in a tributary to the Minnesota River, known as Seven Mile Creek. Within the Park there is an extensive network of ravines ...

Six late Quaternary river terraces, preserved along the Clearwater River in northwestern Washington State, provide a ;140 ka record of long-term incision and uplift across the western side of the Cascadia forearc high. Terrace ages are constrained by weathering rind and radiocarbon dating and by correlation to dated coastal glacio-fluvial deposits and the global eustatic curve. The terraces ove...

River aggradation or incision at different spatial-temporal scales are governed by tectonics, climate change, and surface processes which all adjust the ratio of sediment load to transport capacity a channel. But how river responds differential tectonic extreme events in catchment is still poorly understood. Here, we address this issue reconstructing distribution, ages, sedimentary process fluv...

We present several constructions for terraces for cyclic groups that are zigzag terraces, graceful terraces or both. These allow us to complete the classification of imperfect twizzler terraces, unify several previously unrelated constructions of terraces from the literature, find terraces for some non-cyclic abelian groups, and show that for any given r the Oberwolfach Problem with parameters ...

The Late Quaternary geomorphology and stratigraphy of the Big Fork River valley, within the Rainy River basin of northern Minnesota, reveals evidence of prehistoric human interaction with late Holocene riverine environments. By 11000 14 C B.P., deglaciation made the region inhabitable by human groups using Clovis artifacts. Human habitation would also have been possible during the Moorhead low ...
