Contract 1998 from the Minnesota Geological Survey

Digital files for the Minnesota River Valley Corridor Database Development and Mapping project.
  Dale Setterholm, Project Manager.

The coverages were originally created with ARC/INFO 7.04. Two coverages contain contour lines of bedrock 
topography and drift thickness. One coverage contains polygons showing outcrop locations in the Upper 
Minnesota River valley.  One coverage contains well record information from CWI.  Data in all of the 
coverages is in NAD83.

dtln:  ARC line coverage of the drift thickness.  Contour interval is 50 feet.
 
btln:  ARC line coverage of the bedrock topography.  Contour interval is 50 feet.															 

bgoc:  ARC polygon coverage of outcrops located in the Upper Minnesota River valley.

wwptmrv:  ARC point coverage of the water well locations for the study area

cwi4mrv.mdb -- Access database version of CWI data.
cwi_ver4.doc -- documentation on tables contained in cwi4mrv.mdb in MSWord format.
             Note:  These tables can be linked to the points in wwptmrv by the common item "relateid".

The Arc export files are stored under the subdirectory expfiles.
