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.

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.

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.
