Title:
Locations of near-surface bedrock confirmed using surface geophysics in the Park Falls Unit of the Chequamegon-Nicolet National Forest, Wisconsin
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
A geophysical survey was conducted to confirm locations of near-surface bedrock near the intersection of Gates Lake Road and Forest Road 137 in the Park Falls Unit of the CNNF. These locations were confirmed using surface geophysics by Dave Hart (WGNHS) and Mike Fienen (U.S. Geological Survey) during the summer of 2011. This dataset consists of points near exposed bedrock with the associated geophysical measurement. Two other datasets, PF_GeophysEM31_WGNHS_2016 and PF_GeophysGEM2_WGNHS_2016, contain the complete suite of geophysical results. This geophysical survey was conducted using the EM31 and EM34 conductivity meters manufactured by Geonics Limited and the GEM2 earth conductivity meter manufactured by Terraplus. Both instruments output results of apparent conductivity in millisiemens per meter (mS/m). Survey results and interpretation are documented in an accompanying summary report available from the Wisconsin Geological and Natural History Survey.
Purpose:
This dataset was produced as part of a project to assess groundwater resources across the Chequamegon-Nicolet National Forest. Groundwater is an important resource for the forest, and a more comprehensive understanding of this resource can help guide land management decisions. Geophysical surveys evaluate changes in ground conductivity and can be used to confirm areas of shallow bedrock. Knowledge of bedrock outcrops helps to constrain interpretations of the bedrock surface, which is important for developing a conceptual framework for the hydrogeologic system. The datasets produced as part of this project are divided by location into four groups, corresponding to the four main National Forest Units: Medford, Nicolet, Park Falls, and Washburn/Great Divide. This dataset is located in the Park Falls Unit.
