This page last updated: 2009
Metadata created using Minnesota Geographic Metadata Guidelines

### Metadata Summary

Originator | Minnesota Geological Survey
Abstract | This dataset consists of the locations of wells drilled within Carlton County and the Fond du Lac Reservation. The County Well Index (CWI) is a database that contains geologic information about wells drilled throughout Minnesota. locations were used to look at the geological descriptions of these wells. This CWI dataset was downloaded from the Minnesota Geological Survey (MGS) in June of 2007 and contained 3429 wells within the project's spatial extent.

Browse Graphic File Description |
Associated Data Sets | The Aggregate Resource Mapping Program's spatial datasets for Carlton County and the Fond du Lac Reservation are included in the file carlton_aggregate_data.zip, accessible from the MN DNR Aggregate Mapping web page: http://www.dnr.state.mn.us/lands_minerals/aggregate_maps/completed/index.html The spatial datasets are also available as shapefiles and a file geodatabase stored at drive:\data\resource on the associated CD (where 'drive' is the CD reader or writer drive on the PC). The spatial datasets include: sand and gravel potential, crushed stone potential, field observations, mining pits, depleted mining lands, Minnesota Geological Survey (MGS) County Well Index (CWI) data points, sieve analysis table of selected field observations, MGS CWI stratigraphy table, and Mn/DOT ASIS pit quality table. Selected aggregate resource datasets from this project can also be viewed in the Aggregate Resource Mapping Program's Aggregate Mapper at: http://www.dnr.state.mn.us/lands_minerals/aggregate_maps/online_maps/index.html Aggregate Mapper allows users the ability to work with the aggregate resource data without having to download additional software. The site can display spatial and tabular aggregate resource data such as sand and gravel potential, crushed stone potential, field observations, mining pits, and depleted mining lands. This information can be overlaid on a variety of base map information from Web Mapping Services (WMS) sources like; 1:24,000-scale DRGs (digital topographic maps), 1991 black-and-white air photos, and 2008 Farm Service Agency color air photos.

Vertical Positional Accuracy | Not applicable.
Lineage | The geological descriptions associated with the well locations were used to make interpretations and test interpretations about the geology, aggregate resources, and glacial and bedrock history of the area.

Section 5 | Entity and Attribute Information | Top of full metadata | Top of page
Entity and Attribute Overview | These points represent the locations of individual wells drilled throughout Carlton County and the Fond du Lac Reservation
Entity and Attribute Detailed Citation | Found either at document carlcwiwells0607_att.htm or see table below Attribute values can be found in the table carlcwiwells0607_att.htm. If this table hotlink cannot be found by your browser, you can find this file stored in the same location (i.e., drive:\docs) as this metadata record. carlcwiwells0607.shp contains a field (doh_path) that is used to hyperlink to the Minnesota Department of Health's County Well Index Online webpage. This web page provides detailed information (i.e., Drillers Description, Stratigraphy, etc.) regarding the associated well, via its 'relateid' or unique id. The shapefile can be hyperlinked utilizing ESRI software like ArcView 3.3 and ArcGIS 9. An additional table, carlcwistrat0607.dbf, is a subset of the STRAT table of the CWI database. The carlcwiwells0607 shapefile relates to the carlcwistrat0607.dbf table as a one-to-many relate on the relateid field. The additional table contains only those fields that were considered directly applicable to developing aggregate resource mapping units for this project. Descriptions can vary from well to well, due to different individuals completing the well logging. As an example of the detail found in these descriptions: detailed descriptions often cover 5 to 10 feet of thickness per glacial material type or bedrock type. Less detailed descriptions may say 0-240 feet glacial drift and 240-360 feet sandstone. The definition of the fields found in carlcwistrat0607.dbf are included in the carlcwiwells0607.shp_att.htm

| DEPTH2BDRK |  | Number,19,11 | e.g., 10, 71, 154, 510. -999 indicates no data. | Describes in feet the depth to the first bedrock encountered.
| DOH_PATH |  | Text, 125 | e.g., http://mdh-agua.health.state.mn.us/cwi/well_log.asp?wellid=0000732429 | A URL hyperlink that links, using ESRI software like ArcView 3.3 or ArcGIS 9, to the associated well’s information (i.e., stratigraphy, drillers description) displayed via the county well index online web page, provided by the Minnesota Department of Health. Some wells are not available on this site. More information about this page can be found at: http://www.health.state.mn.us/divs/eh/cwi/
carlcwistrat0607.dbf |  |  |  |  | Associated table for use with mcwiwells.shp. Relate the table with the shape on the field relateid. There is a one-to-many relationship between the shapefile and this table. This table is a subset of the data stored in the C4ST (i.e., driller’s description, interpreted stratigraphy) of the MGS CWI database.
