in P.J. Hoffmaster State Park
of Homestead Trail parabolic dune (Dune 1)
summer 2008, Luke Pettinga (assisted by Jenna Beauchamp) and Deanna van Dijk studied the Homestead Trail parabolic dune (Dune 1) to document its characteristics and activity in comparison with a 2002 study of the same dune. The project included surveying and mapping
Dune 1, measuring erosion pins, and using GIS to compare results from this study and the study completed in summer 2002.
This study was supported by a Davis A. Young Student Research Fellowship and the Department of Geology, Geography and Environmental Studies at Calvin College.
of Mount Baldy and Other Parabolic Dunes
summer 2006, David Meyer and Deanna van Dijk studied Mount
Baldy in comparison to other large parabolic dunes in and near P.J.
Hoffmaster State Park. The project included surveying and mapping
Mount Baldy and using aerial photographs and site visits to investigate
other parabolic dunes. Data and images from the Mount Baldy study
will be used on new interpretive materials in preparation by the
Department of Natural Resources.
This study was supported by the Calvin College Science Division.
Study of Coastal Dune Changes
October 2000, Deanna van Dijk and students have been monitoring
coastal dune changes in Hoffmaster State Park including the growth
of a foredune and changes to a blowout. The multi-year study focuses
on sediment movement and important variables (e.g. winds, frozen
ground, beach width) in the fall and winter when the strongest local
winds occur. The research was described in a 2002
Calvin Spark article as well as publications
This study has been supported by the Calvin College Science
Division, Calvin College Alumni Association, and the Department
of Geology, Geography and Environmental Studies at Calvin College.
Study of Annual Changes to Lake Michigan Coastal Dunes
This one-year study investigated seasonal patterns of coastal dune
change in a four-season study of foredune and blowout changes. Study
outcomes include interpretive materials for Hoffmaster State Park
and this web-site on Lake Michigan coastal dunes.
This study was supported by a Michigan Coastal Management Program
