Task 2-Quaternary Geologic Mapping and Subsurface Correlation

Science Center Objects

The area encompassed by Task 2 includes various regions on the margins of the Great Lakes, with initial focus on: (1) several counties along the east margin of Lake Michigan (Leelanau, Benzie, Manistee, and Mason Counties of Michigan); and (2) Berrien County of southwestern Michigan.  The primary objective of Task 2 is to produce a seamless, zoomable geologic framework map geodatabase in GeMS format that includes the following data: Quaternary surficial map units on the basis of new LiDAR data; Quaternary sediment thickness and subsurface characterization tied to borehole and geophysical data; subcropping bedrock geology (including areas beneath the Great Lakes that are integrated with bedrock exposures); borehole data; Great Lakes bathymetry; grids of the upper surfaces of extant Paleozoic strata; and subsurface lithologies constrained by available borehole data.  These geologic data have been requested through partnerships with the U.S. National Park Service (Leelanau and Benzie Counties) and the U.S. National Forest Service (Manistee and Mason Counties).
