The map area contains the St. Croix horst, a rift graben filled with Mesoproterozoic rocks of the Keweenawan Supergroup that was subsequently inverted. The horst exposes about 15 - 20 km of strata that record the opening of the Midcontinent rift, its subsequent transition to a thermal subsidence basin, and eventual inversion. About 3 km of underlying Mesoproterozoic strata, including the Gogebic iron range, and about 10 km of Neoarchean rocks, exposed in the southernmost part of the map area lie to the southeast of the horst. The nearly flat-lying continental red beds of the Oronto and Bayfield Groups, the youngest strata of the Keweenawan Supergroup, overlie the volcanic rocks. A wealth of geologic data exists for the area as a result of many individual studies over the last hundred years, but much has remained unpublished in theses, dissertations, and other reports of limited availability. This map has incorporated most of that data (see list of data sources) and includes results of our investigations conducted from 1992 to 2000. Our studies were designed to fill gaps in existing data and reconcile conflicting interpretations on some aspects of the geology of the region. Purpose: The purpose of this map is to complete digital coverage of quadrangles with significant exposure of rocks of the Midcontinent rift in Wisconsin and Michigan at a scale of 1:100,000. Other maps in this series include the bedrock geologic maps of the Ontonagon-Wakefield, the Ashland-Ironwood, and the Keweenaw Peninsula areas (USGS Open-File Reports 01-088, 99-546, and 99-149, respectively). Supplemental_Information: The coverages included are as follows: geology, faults, outcrops, structure, drill_holes, county_lines, xsect_line, form_lines, rock_quarries, age_dates, and xsect_geology.

Vector and polygon attributes were obtained from field maps and observations and other sources. Linear features were compiled from field maps and inferred from aeromagnetic data and seismic reflection lines. The locations of the radiometric age samples and other geochemical samples were obtained by heads-up digitizing field station locations on field maps. Mineral deposits and quarries were located by heads-up digitzing from descriptions and maps in several reports. Logical_Consistency_Report: All internal polygons were checked for closure with vendor software and on hard copy plots. Overshoots and undershoots have been deleted or corrected as appropriate. Completeness_Report: Although, the coverage of the cross section A to A' (xsect_geology) contain attributes and georeferencing information, they are not true geographic data. Rather, they were structured as coverages to allow correct scaling and positioning with respect to map view data. This allows the user to view the cross sections in relation to the geologic units.

Projected in UTM Zone 15, NAD27, meters, longitude at central meridian -93 0 0 and latitude of projection origin 0 0 0. Process_Date: 20030416 Process_Step: Process_Description: Location of outcrops were compiled from many sources of paper maps at various scales. They were compiled onto paper copies of 1:100,000 topographic maps and heads-up digitized onto digital raster graphics files of the quadrangles. Additional outcrops were located during field studies and compiled on 1:24,000 and 1:100,000 topographic maps. These also were digitized by heads-up method onto digital raster graphic 1:100,000 topographic maps. Geology lines and faults were interpreted from outcrop and geophysical data and were drawn digitally. Converted shapefile to a coverage and extended the lines to create a polygon coverage. Built the coverage to create topology. Polygons were checked for closure. Added ID to the polygon attribute table. Tagged each polygon with the corresponding id and joined an attribute table to the ID field. Exported file as geology.e00. Source_Used_Citation_Abbreviation: geology_lines Process_Date: 20030416 Process_Step: Process_Description: The outcrops were heads-up digitized in ArcView from 7.5 minute and 100k quad paper field maps. 7.5 minute quads used: >Bennett >Black Lake >Borea >Brule >Buckety Creek >Cloverton >Dairyland >Empire Swamp >Lake Nebagamon >Moose Junction >Oulu >Patzau >Poplar >Scovils Lake >South Range >Sunnyside 100k quads used: >Port Wing >Solon Springs >Duluth >Sandstone The coverage outcrops was edited using ArcEdit. Polygons were checked for closure. Overshoots and undershoots were deleted or corrected as appropriate. The file was built to create polygon topology. The coverage was compared to the paper map. Corrections were made when needed. Coverage was exported as an .e00 file. Source_Used_Citation_Abbreviation: outcrop field sheets Process_Date: 20030108 Process_Step: Process_Description: Original well data from Bear Creek Exploration Company. Data transfered from well sheet to 100k topo sheet to the nearest 1/16th of a section. Then data was heads-up digitized in ArcView as a point shapefile. ID column was added as a unique value for each well. File was exported to create an .e00 file. Source_Used_Citation_Abbreviation: well data Process_Date: 20020321 Process_Step: Process_Description: County_lines coverage was clipped from ESRI map data. A box was created to capture the map area and then the ESRI county coverage was clipped to the box. File was exported to create an .e00 file. Source_Used_Citation_Abbreviation: county_lines Process_Date: 20030421 Process_Step: Process_Description: The structure coverage was created by heads-up digitizing the locations. Data had "dip", "reference", "type", and "rotation" columns added to the point attribute table. The symbols were rotated based on the rotation column in order to be in the correct orientation (representing strike). File was exported as an .e00 file.
