Fargo/Moorhead Study [FMS]

Digital products - database

Included in this archive are the point coverages shapefiles
and associated statigraphic database files that were used
in preparing the geologic maps and models for the project.

  fmsindex1212.shp - main drill hole database used for interpretation
     and creation of the 3D model.  Based on data from the County
     Well Index in Minnesota, with additional data (reformatted to
     match the CWI index and strat tables)from the State Water 
     Commision in North Dakota, the Whapeton Buried Valley study, 
     and other small data collections.

     The data were cleaned and enhanced by Jim Berg (MnDNR) prior
     to their use for generating cross-sections used for developing 
     the 3D model.

  fmsst_1212.dbf - downhole stratigraphic interval database for
     relational use with fmsindex1212.shp

Addtional datasets used in developing the geologic interpretation
presented in the surficial and bedrock geologic maps include:

  qtptfms - data points for sampling of Quaternary/Holocene materials
     including giddings probe sites and hand sample sites.

  sbptndix.shp - point index of engineering test borings in North
     Dakota from NDGS RI 60, "Stratigraphy of Offshore Sediment,
     Lake Agassiz - North Dakota" by Mike Arndt

  mndotfms - engineering test borings from the Mn Dept.of Transportion.

All layers are provided as shapefiles in the FMS projection, which is:

   Lambert projection 
   units: meters
   1st std parallel: 33 00 00
   2nd std parallel: 45 00 00
   central meridian: -96 30 00
   origin parallel : 45 00 00

 using the NAD83 datum.
