Sand stringers are subtle (~1-10 m high), elongate (several km long, up to 100 m wide) aeolian landforms that lack a slip face and generally have a northwest-southeast orientation. They are ubiquitous across the Upper Midwest, including southeast Minnesota and western Wisconsin. Despite their prevalence, the timing, processes, and environmental conditions during sand stringer formation and evolution are poorly understood. This research aims to describe sand stringer morphology and stratigraphy, reconstruct regional paleoclimate, and characterize the timing and geomorphic processes of sand stringer formation and evolution in response to shifts in environmental conditions. This study investigates two sand stringers: Good-1 …

Modern land use has dramatically altered the native landscape across much of Minnesota and the United States. “Manifest Destiny” has ingrained the idea in American society that wetlands and related lands of “low value” need to be tamed and made profitable. In many places, wetlands have been drained and removed so that agriculture can take over. In recent years, people have begun to see the unintended consequences of this method, and importance is now being given to natural wetlands through various government projects and programs. Using National Wetlands Inventory (NWI) data, Drainage Index (DI) values calculated from Soil Survey Geographic …
