About this file
This is a Geophysical Survey Report prepared for the Michigan Department of Natural Resources by Materials Testing Consultants, Inc. in September 2014. The report documents a comprehensive geophysical investigation conducted at F.J. McLain State Park in Houghton County, Michigan, with the primary objective of assessing coastal zone geology, bluff recession rates, and subsurface conditions. The survey employed electrical resistivity testing, soil boring analysis, and GPS data collection across a grid-based investigation area. The work incorporated literature reviews of historical data from 1982 through 2014, including NOAA buoy station records, prior erosion studies, shoreline stability assessments, and Michigan Technological University geophysics reports. The investigation included 40 test borings, 9 resistivity survey lines, and monitoring of recession stakes established by DNR personnel to track bluff migration over time.
The report presents detailed geological findings regarding the Keweenaw Peninsula bedrock topography, coastal geomorphology, and Lake Superior bathymetry relative to longshore sediment transport patterns. Key deliverables include interpolated bedrock surface contours, boring logs with soil classification data, resistivity logs, photographic documentation, and a quality assurance/quality control project plan. The investigation was designed to support DNR decision-making regarding coastal erosion management and park infrastructure protection, with data appendices providing technical supporting documentation including the DEQ Bluff Recession Rate Analysis and acknowledgments from the Department of Environmental Quality, Coastal Zone Management, and NOAA.
