Lineage | This layer was created as part of the county-wide aggregate mapping program to show the locations of existing aggregate sources, active, inactive, or reclaimed. The gravel pit locations were gathered from a variety of sources, including the Soil Survey of Wright County (from the Soil Conservation Service), 15-minute USGS topographic maps, Minnesota Department of Transportation Wright County Highway Map, Wright County Highway Department files, and field observations by the author, JD Lehr.

Entity-Attribute Overview | Gravel pit and aggregate sources locations, with a field to indicate if they were or were not shown on the map.
Entity-Attribute Detailed Citation | The complete table is listed below:

Table Name | Field Name | Begin Column | Definition | Valid Values | Descriptions
gp90xpt3 shapefile |  |  |  |  | Gravel pit and aggregate source locations
| pitno |  | Number,2,0 |  | Gravel pit or aggregate source, given as a number
|  |  |  | 50 | Gravel pit - locations gathered from several sources. In places single symbols indicate multiple gravel pits. May be active, inactive, depleted, or reclaimed.
|  |  |  | 90 or 99 | MN/DOT identified aggregate source. Test hole logs, sieve and quality data were available. Typically include gravel pits.
| pittype |  | Text, 5 |  | Gravel pit or aggregate source, given as text
|  |  |  | Other | Gravel pit locations derived from a number of sources, including the Soil Survey of Wright County, Wright County Highway Department files, observations by the author.
|  |  |  | MNDOT | Gravel pit locations from MN/DOT source materials.
| drawmap |  | Text,1 |  | Indication of whether or not the gravel pit location was drawn on the map
|  |  |  | Y | The gravel pit was drawn on the map
|  |  |  | N | The gravel pit was not drawn on the map because there were several in the same location, so one symbol, not several, was used to represent them.
