edited by Timothy G. Fisher and Edward C. Hansen

The 17,500 km of Great Lakes’ shoreline—North America’s “third coast”—has been the
setting for a number of classic studies in coastal geomorphology and Quaternary geology,
especially on the subjects of coastal dunes and the effects of deglaciation and isostatic
rebound on lakes and coasts. Speaking to a recent revival of interest in these processes
along the Great Lakes, this volume includes an interdisciplinary mix of papers spanning a
variety of temporal scales and offering a substantive overview of this recent research. The
majority of the papers investigate the relationship between dune activity, lake levels, and
climate. In addition to offering insights into coastal processes in general, the data presented
here could help inform decisions on how to manage and mitigate the human impact on this
fragile natural environment.

E$-9b.o99ok Insights into the Michigan Basin: Salt Deposits, Impact Structure, Youngest Basin
Bedrock, Glacial Geomorphology, Dune Complexes, and Coastal
Bluff Stability

Edited by Robb Gillespie

This volume is a compilation of field excursions from the 2013 GSA North-Central Section
meeting held in Kalamazoo, Michigan. Early depositional events within the Michigan Basin
are examined deep underground in the Detroit Salt Mine. The Kentland Quarry (northwest
Indiana), the site of a Cretaceous-aged meteorite impact, permits surface examination
of a similar impact event that occurred in now-buried Ordovician-aged rocks in Cass
County, Michigan. A trip near Grand Ledge, Michigan, examines Mississippian-aged fluvial
deposits traditionally classified as the youngest bedrock exposed in Michigan. Younger,
recently identified, Pennsylvanian rocks are the subject of a core workshop at the Michigan
Geological Repository for Research and Education in Kalamazoo. Three trips showcase
the surficial geology of southwest Michigan: One trip details the glacial landforms and
sedimentary features formed by the differing dynamics of the Laurentide Ice Sheet’s
Michigan and Saginaw lobes. The other trips follow the eastern Lake Michigan shoreline and
examine sand-dune complex development and coastal bluff stability and erosion issues.
