### Metadata Summary

Originator | Minnesota Geological Survey & MN Department of Natural Resources, Division of Lands and Minerals, Mineral Potential Section, Aggregate Resource Mapping Program
Abstract | This dataset consists of bedrock geology mapping units for Mille Lacs County, Minnesota. The bedrock geology is compiled from two Minnesota Geological Survey (MGS) miscellaneous map series [Bedrock Geology of Mille Lacs 30 x 60 Minute Quadrangle (1:100,000, M-100, 1999) and Bedrock Geology and Superimposed Magnetic on Gravity Anomaly of for East-Central Minnesota (1:200,000, M-132, 2003), as well as, a MN DNR general bedrock geologic interpretation of the southeast corner of Mille Lacs County at a 1:200,000 scale where MGS data was not available.

Ordering Instructions | Go to the website of the Minnesota Geological Survey, http://www.geo.umn.edu/mgs, to find Misc. Map Series M-100 and M-132 for maps and GIS data. To download the merged Bedrock Geology of Mille Lacs County which was used for this project and downloaded in 2005 and processed in 2006, go to http://www.dnr.state.mn.us/lands_minerals/aggregatemaps.html, where it is part of the Aggregate Resource Mapping Program's datasets for Mille Lacs County in the file milldata.zip. The datasets are also available as aggregate resource data layers stored at drive:\data\resource on the CD (where 'drive' is the CD reader or writer drive on the PC). The datasets include data on sand and gravel potential, crushed stone potential, overburden model source points, field observations, aggregate pits and quarries, County Well Index (CWI) data sources, field observation's sieve database, and MN DOT ASIS pit quality database. In addition, selected Mille Lacs aggregate resource datasets can 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 with little to no GIS experience the ability to work with GIS data. The site can display spatial and tabular aggregate resource data such as sand and gravel potential, crushed stone potential, field observations, and gravel pits. This information can be overlaid on a variety of reference information from Web Mapping Services (WMS) sources like 1:24,000-scale DRGs (digital topographic maps), 1991 black-and-white air photos, and 2003-04 Farm Service Agency color air photos.

Title | Mille Lacs County Aggregate Resource Evaluation - Bedrock Geology Hybrid, Mille Lacs County, 1999-2006 - millmgsbg
Abstract | This dataset consists of bedrock geology mapping units for Mille Lacs County, Minnesota. The bedrock geology is compiled from two Minnesota Geological Survey (MGS) miscellaneous map series [Bedrock Geology of Mille Lacs 30 x 60 Minute Quadrangle (1:100,000, M-100, 1999) and Bedrock Geology and Superimposed Magnetic on Gravity Anomaly of for East-Central Minnesota (1:200,000, M-132, 2003), as well as, a MN DNR general bedrock geologic interpretation of the southeast corner of Mille Lacs County at a 1:200,000 scale where MGS data was not available.
Purpose | For the purposes of mapping crushed stone resources, three bedrock datasets are merged and reinterpreted with respect to aggregate potential to produce a generalized bedrock map of the county. The reinterpretation can be seen in attribute field 'DNR_Reclas'. For more detailed MGS geologic descriptions refer to attribute field 'MGS_Desc' which is a verbatim copy of the two MGS datasets.
