Title | INDUSTRIAL CLAY OCCURRENCES IN THE MINNESOTA RIVER VALLEY IN PORTIONS OF CHIPPEWA, YELLOW MEDICINE, RENVILLE, REDWOOD, BROWN, BLUE EARTH, NICOLLET, AND LESUEUR COUNTIES |
Abstract | This data set contains the locations of industrial clay occurrences in portions of Chippewa, Yellow Medicine, Renville, Redwood, Brown, Nicollet, Blue Earth, and Le Sueur Counties, Minnesota, that lie in or near the Minnesota River Valley, including the Redwood, Cottonwood, Watonwan, Blue Earth, and Le Sueur river valleys. The clay occurrences have been documented from mine pits, quarries, and gravel pits; outcrops; river, stream, and road cuts; drill core; and hand-auger samples. |
Purpose | To provide a data set of known industrial clay occurrences in this portion of the Minnesota River Valley to aid in planning for land use and resource availability. |

Attribute Accuracy | Accuracy of attributes is not known. |
Logical Consistency | |
Completeness | Clay occurrences depicted are taken only from NRRI studies and from Parham and Hogberg, 1964. As such, they do not include all known clay occurrences in the Minnesota and adjoining river valleys within the study area. |
Horizontal Positional Accuracy | The horizontal positional accuracy of the data set varies as follows: drill hole and sample collection site (surveyed by GPS): +/-1 meter drill hole and sample collection site (surveyed not by GPS): +/-5 meters historical data: 10 meters to 1/4 Section |
Vertical Positional Accuracy | n/a |
Lineage | Zanko et al. data was produced by Zanko in AutoCAD by drawing over inserted, georeferenced, Digital Orthophoto Quads. Parham and Hogberg, 1964, and Toth, 1991, data were reproduced from a digital AutoCAD map produced by Toth in 1990. It is likely that the Parham and Hogberg, 1964, locations were digitized into AutoCAD from the map contained in their published report. Drill hole data were plotted as points by UTM coordinates in AutoCAD.
