I study the landforms and landscapes left behind by the Ice Age–how they were formed, how they are changed by today’s geologic processes, and what resources they contain (such as gravel and groundwater). These projects employ tools such as active seismic surveys, structure-from-motion elevation models with drone photogrammetry, and optical age estimates that help to constrain the stratigraphy and timing of Pleistocene glacial events in Wisconsin. I’m also actively involved in mapping the Quaternary geology of Bayfield, Sawyer, Ashland, Price, and Burnett counties (1:100,000 scale), and in creating a Quaternary and bedrock elevation map of the state of Wisconsin (1:500,000 scale).
Current projects
A few projects I’m working on are:
- glacial geology in the Central Sands and Lake Superior Region,
- shoreline erosion in Lake Michigan, and
- the effects of ice cover on shoreline erosion on Lake Superior.
My current projects can be explored through this interactive map:
