Gravel pits were digitized
from 1:24,000 USGS quadrangles, were located by field work, or were obtained
from other sources; aggregate sources were obtained from the Minnesota
Department of Transportation. |

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. |

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. |
