Metadata Summary

Originator Minnesota Department of Natural Resource, Division of Lands and Minerals, Mineral Potential Evaluation Section
Abstract This dataset includes information gathered in the field. Fieldwork was completed in the spring and fall of 2008. It includes 1212 field observation sites within Carlton County and the Fond du Lac Reservation. Observations include, but are not limited to: aggregate pits (gravel pits, sand pits), clay pits, and borrow pits; test holes; exposures of surficial geologic sediment, glacial stratigraphy, and bedrock formations in road cuts or along stream banks; excavations for basements, judicial ditches, construction projects, and trenches (cable, pipe, tiling). This spatial dataset contains a field description of each site, the dominant type of material encountered, the source of information, geologic unit thickness, and geologic overburden thickness. A selected number of observation's geologic sediment were sampled and analyzed with a sieve. A table was created based on the sieve analysis that can be joined to this dataset's unique observation id (see associated datasets)

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.

Title Carlton County and Fond du Lac Reservation Aggregate Resource Evaluation - Field Observations - carlfobs
Abstract This dataset includes information gathered in the field. Fieldwork was completed in the spring and fall of 2008. It includes 1212 field observation sites within Carlton County and the Fond du Lac Reservation. Observations include, but are not limited to: aggregate pits (gravel pits, sand pits), clay pits, and borrow pits; test holes; exposures of surficial geologic sediment, glacial stratigraphy, and bedrock formations in road cuts or along stream banks; excavations for basements, judicial ditches, construction projects, and trenches (cable, pipe, tiling).

A selected number of observation's geologic sediment were sampled and analyzed with a sieve. A table was created based on the sieve analysis that can be joined to this dataset's unique observation id (see associated datasets)
Purpose To summarize the field observations collected in Carlton County and the Fond du Lac Reservation. These observations were made to confirm air photo interpretation that identified potential aggregate bearing landforms.

Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy
Logical Consistency
Completeness The data points were gathered at the location where field observations took place. Additional information is given in the Lineage section.
Horizontal Positional Accuracy The differential correction of the GPS unit for GPS located sites is +/- 2 meters.
Vertical Positional Accuracy Not applicable.
Lineage A tablet PC, a GPS unit (Garmin Etrex), ArcGIS 9.3 software, and the GPS toolbar in ArcGIS 9.3 were used in the field to determine the track and location of the observer collecting the points. Field observation points were digitized in real time, as well as, the entered tabular attribute information. The combination of the GPS unit's location, USGS topographic maps (1:24,000), and aerial photographs (1:3,000 - 1:12,000) were used to assist in determining the observation's site location on screen. The GPS unit (with differential correction) is accurate to approximately a few meters.
