Metadata created using Minnesota Geographic Metadata Guidelines

### Metadata Summary

Originator | Department of Natural Resources, Division of Lands and Minerals, Mineral Potential Evaluation Section
Abstract | This dataset consists of location information, source information, and geological characteristics for 424 mining pits (372 Gravel Pits, 33 Sand Pits, 16 Borrow Pits, and 3 Clay Pits) within Carlton County and Fond du Lac Reservation that are currently being mined or have been mined. Several sources of information identify pit locations: topographic maps, aerial photographs, soil surveys, Mn/DOT (Aggregate Source Information System) ASIS files, fieldwork, gravel operators, and other miscellaneous sources. Pits range in size from less than 1 acre to greater than 50 acres and may be active, inactive, or reclaimed. The aggregate quality of the pit varies.

Currentness Reference | Source information in the pit shapefile was collected from the following: field work, soil survey, topographic maps, aerial 7.5 minute topographic quadrangles, and ASIS (Aggregate Source Information System). Pits were identified during field work in the spring and fall of 2008 and the spring of 2009. Pit locations were digitized and edited in ArcGIS 9;3 either in real time while in the field or in the office. U.S. Geological Survey, 7.5 minute topographic quadrangles at a scale of 1:24000. The age of the quadrangles range from 1967 to 1983, with some quads photo revised in 1994. The aggregate pits located from the Soil Survey are from 2008. Pits from aerial photographs are identified from NAPP (National Aerial Photography Program), 1991-1992, 9 inch by 9 inch color infared photographs at 1:40,000, Farm Service Agency (FSA) air photos from 2003-04, 2005, 2006, and 2008. ASIS data points were acquired from the Minnesota Department of Transportation in January of 2008.

Ordering Instructions | 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.

Horizontal Positional Accuracy | These points were captured from several different sources, including USGS 1:24000 quadrangles, 1:12000 USGS DOQs (from 1991), Farm Service Agency (FSA) color air photos (from 2003-04, 2005, 2006, 2008), Natural Resource Conservation Service Soil Survey point data, and the ASIS (Aggregate Source Information System) dataset from the Minnesota Department of Transportation. Points captured in the field were assisted with a GPS (+/- 2 Meters), Tablet PC, and ArcGIS 9.3.
Vertical Positional Accuracy | Not applicable.
Lineage | These points were captured from several different sources in the winter of 2008 (Feb-Apr), including USGS 1:24000 quadrangles, 1:12000 USGS DOQs (from 1991), Farm Service Agency (FSA) color air photos (from 2003-04, 2005, 2006, 2008), Natural Resource Conservation Service Soil Survey point data, and the ASIS (Aggregate Source Information System) dataset from the Minnesota Department of Transportation. The pits captured were edited in the field during the Spring and Fall of 2008 with a GPS (+/- 2 Meters), Tablet PC, and ArcGIS 9.3. The gravel pits that are medium (5-15 Acres) to large (15+ Acres) are located somewhere in the disturbed area, and should be very accurate.
