Additonal Information

  • The Aggregate Sources layer consists of two main categories: 1) Mn/DOT owned pits, and 2) those owned by others that may, or may not, be leased by Mn/DOT. There is also an "All Aggregate Sources" folder that contains all pits regardless of owner or status.
  • Unavailable sources are most likely not available for further mining.
  • Identifying or selecting aggregate sources returns an Excel spreadsheet as shown below.
  • If the source number in the leftmost column is blue, a pitsheet (Adobe pdf) can be viewed by clicking on the source number.
  • The Excel spreadsheet can be saved to your computer.

  • The Report Tab, in the Table of Contents Frame, allows you to search for aggregate source data by entering Aggregate Source Number, District, County, or Section-Township-Range. The resulting report is an Excel spreadsheet as shown above. The Report only searches the Active Select Layer.
